I have had office professional edition since 2005 on my pc. Now it is saying I need to validate it again. I try ringing up and it says the number I am giving is not valid. Here is a report with the diagnostic tool- Diagnostic Report (1.9.0011.0): ----------------------------------------- WGA Data--> Validation Status: Genuine Validation Code: 0 Cached Validation Code: N/A Windows Product Key: *****-*****-BRVBB-38MQ9-3PMFT Windows Product Key Hash: 2V2VyxlfhiaCt/JkDzYQfiNOHMA= Windows Product ID: 76477-OEM-2111907-00106 Windows Product ID Type: 2 Windows License Type: OEM SLP Windows OS version: 5.1.2600.2.00010300.3.0.hom ID: {597A5F74-2379-4BCB-B23D-98D6BFC8C4E4}(1) Is Admin: Yes TestCab: 0x0 WGA Version: Registered, 1.7.69.2 Signed By: Microsoft Product Name: N/A Architecture: N/A Build lab: N/A TTS Error: N/A Validation Diagnostic: 025D1FF3-230-1 Resolution Status: N/A WgaER Data--> ThreatID(s): N/A Version: N/A WGA Notifications Data--> Cached Result: 0 File Exists: Yes Version: 1.7.18.5 WgaTray.exe Signed By: Microsoft WgaLogon.dll Signed By: Microsoft OGA Notifications Data--> Cached Result: N/A, hr = 0x80070002 Version: N/A, hr = 0x80070002 OGAExec.exe Signed By: N/A, hr = 0x80070002 OGAAddin.dll Signed By: N/A, hr = 0x80070002 OGA Data--> Office Status: 101 Not Activated Microsoft Office Professional Edition 2003 - 101 Not Activated OGA Version: N/A, 0x80070002 Signed By: N/A, hr = 0x80070002 Office Diagnostics: 025D1FF3-230-1_3E121E02-565-80004005_3E121E02-277-80004005 Browser Data--> Proxy settings: N/A User Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32) Default Browser: C:\Program Files\Mozilla Firefox\firefox.exe Download signed ActiveX controls: Prompt Download unsigned ActiveX controls: Disabled Run ActiveX controls and plug-ins: Allowed Initialize and script ActiveX controls not marked as safe: Disabled Allow scripting of Internet Explorer Webbrowser control: Disabled Active scripting: Allowed Script ActiveX controls marked as safe for scripting: Allowed File Scan Data--> Other data--> Office Details: <GenuineResults><MachineData><UGUID>{597A5F74-2379-4BCB-B23D-98D6BFC8C4E4}</UGUID><Version>1.9.0011.0</Version><OS>5.1.2600.2.00010300.3.0.hom</OS><Architecture>x32</Architecture><PKey>*****-*****-*****-*****-3PMFT</PKey><PID>76477-OEM-2111907-00106</PID><PIDType>2</PIDType><SID>S-1-5-21-1905328589-3053350881-2744935556</SID><SYSTEM><Manufacturer>HP Pavilion 061</Manufacturer><Model>PX638AA-ABU t3065.uk</Model></SYSTEM><BIOS><Manufacturer>American Megatrends Inc.</Manufacturer><Version>3.19 </Version><SMBIOSVersion major="2" minor="3"/><Date>20050310000000.000000+000</Date><SLPBIOS>HP PAVILION</SLPBIOS></BIOS><HWID>D7EE3C8701844E7D</HWID><UserLCID>0809</UserLCID><SystemLCID>0409</SystemLCID><TimeZone>GMT Standard Time(GMT+00:00)</TimeZone><iJoin>0</iJoin><SBID><stat>2</stat><msppid></msppid><name>Hewlett-Packard</name><model>Pavilion</model></SBID><OEM/><GANotification><File Name="WgaTray.exe" Version="1.7.18.5"/><File Name="WgaLogon.dll" Version="1.7.18.5"/></GANotification></MachineData><Software><Office><Result>101</Result><Products><Product GUID="{91E30409-6000-11D3-8CFE-0150048383C9}"><LegitResult>101</LegitResult><Name>Microsoft Office Professional Edition 2003</Name><Ver>11</Ver><Val>ADAFF82FDA56DA2</Val><Hash>xQ32wr3miJzsH9mCSF9iQy1Bj34=</Hash><Pid>73931-721-9110782-57521</Pid><PidType>1</PidType></Product></Products><Applications><App Id="15" Version="11" Result="101"/><App Id="16" Version="11" Result="101"/><App Id="18" Version="11" Result="101"/><App Id="19" Version="11" Result="101"/><App Id="1A" Version="11" Result="101"/><App Id="1B" Version="11" Result="101"/><App Id="44" Version="11" Result="101"/><App Id="A1" Version="11" Result="101"/></Applications></Office></Software></GenuineResults> Licensing Data--> N/A HWID Data--> N/A OEM Activation 1.0 Data--> BIOS string matches: yes Marker string from BIOS: 1764C:GENUINE C&C INC|10521:Hewlett-Packard Company Marker string from OEMBIOS.DAT: HP PAVILION OEM Activation 2.0 Data--> N/A
