I had originally done a system restore to about three weeks ago but still got the same result so I undid the restore. Then I just did a system restore to May 2007 just after I installed the new version of Microstudio and it started to work. I decided to undo that restore and just try other restore points closer to todays date and see if I could determine when it broke. However, when I undid that restore and came back to the present state of the PC Microstudio now works! I have no idea why but it seems to be fine now. I'll just keep an eye on it I guess...
