Cannot open Microsoft Office 2004

Question

Hi. I have MS Office 2004 installed on my iMac, for using Excel and Word. All of a sudden this morning, I could not print an Excel file, due to some sort of error. Don't know what it was. I then found that I could not open any Office application. I get the message Excel has encountered a problem and needs to close. I have tried uninstalling and reinstalling Office to no avail. I am not too worried about data loss as I did a backup of these files last night. All other programs seem ok, just cannot open any files in Office. Can anyone advise me on my next course of action please?
None of the obvious remarks about using MS please. :-))

Don't know about billy but I did everything. Uninstalled all plists, preferences, reinstalled, nothing worked. BTW, Kurt, the uninstaller also performed like the other Office apps...sometimes it worked, sometimes it didn't.
I also stripped my regular login account of all startup items (at least those that I could do without). Nada.
But I THINK I've found the problem (at least at my end). I had recently installed Shapeshifter's New UB program. When I uninstalled, all Office apps have been performing normally. So I believe this was causing some kind of a conflict for me.
Don't know if that's an actual solution, but it does seem to have done the trick for me.
