I'm using Office 2007 in Windows 7 ultimate. Once I installed Uniblue SpeedUpMyPC to speed up my system. The damn software deleted some important files for which whenever I'm trying to open any saved word document (by double clicking the file) a message: "There was a problem sending command to the program" is coming out and the document is not opening. But after clearing out the message if I double click the file second times (Microsoft word is still opening) then it opens. But after closing the word if I try to reopen the document same problem arises.
I've repaired office installation, even I uninstalled and reinstalled it. But the problem is not solved. Please help me! I'll be grateful to one who can solve this problem.

I suggest stopping the SpeedUpMyPC program first
and see if that issue persist

To stop:
click the WINDOWs icon

run [msconfig]

under services or startup tab, uncheck that program
close MSCONFIG

then start PC again
and open WORD

if the problem goes away, may be reconsidered if you want SpeedUpMyPC

if not, hmm.. have to think again

Thanks a lot for your reply. But its worthwhile to say that after facing such problem I wiped out all the trace of that damn software then and there. Still the problem remains and that's the problem. If you have any solution please help me.
