Hi Sean,
The MGA Diag tool, creates support files when it is run. I do not use those files because there is no way to post files in the forum. The error message you received is just telling you that those support files failed to be created. However, you should still be able to click the 'Copy" button and then Paste the report into this thread, regardless if those support files were created or not.
If you still have problems copying the Report, create a no cost support request at
http://support.microsoft.com/gp/contactwga for further assistance with your Non-Genuine issue.
Thank you,
Darin MS
