I Have resolved this but as I couldn’t find the solution on here I thought I would post a solution that worked for me.
I worked through all the suggestions here...
http://social.microsoft.com/Forums/en-US/tabspace/thread/52033768-d35e-4361-b895-dd33ed0d2d92
none of which worked but I think the only worthwhile fix from that was
goto start bar type cmd then shift+ctrl+enter (not just enter unless UAC is off)
then type regsvr32 jscript.dll + enter
then type regsvr32 vbscript.dll + enter
But in addition to this I had to then type ...
regsvr32 wmp.dll + enter
This additional reg command seemed to fix it
Ok Cheers
