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.
