Microsoft Office Closes Upon Opening Application or Document

I have Microsoft Office 2007 with Word, Excel, Powerpoint, and OneNote. My 
operating system is XP. Whenever I open any of these applications or any 
Word, Excel, or Powerpoint document, the application immediately closes 
saying (in the case of a Word document this just happened with) "Microsoft 
Office Word has encountered a problem and needs to close. We are sorry for 
the inconvenience. 

When I clicked on "What data does this error report contain, I get the 
following:

AppName: winword.exe
AppVer: 12.0.6504.5000
AppStamp: 49e7f5b6 (but I'm not sure if the "f" is an f, an "i" or "l")
ModName: olconnector.dll
ModVer: 2.0.3009.0
ModStamp: 4a2e1608
fDebug: 0
Offset: 0011561

I've moved all my Office documents to a separate external drive and planned 
to uninstall Office 2007 from my system and then reinstall it, but then I'll 
have to figure out which updates I need (or will the system figure that out 
for me?) and I thought that maybe you have a better solution.

Thanks!

Well the module is that for the Outlook Connector, do you use the Connector 
within Outlook?
There's no need to move Office Docs, since an uninstall has no impact on 
docs/data
Presumably you've run Office Diagnostics?

MS Update will show what critical updates are required, checking history 
will also show any failed updates

Hi,

I used Office Diagnostics, and all is fine.

I uninstalled Office 2007 and reinstalled it, and the problem remains.

Outlook Connector is a plug-in, right? I don't use it, but I must have it 
since, when I looked at my installed programs, plugins, etc. Outlook 
Connector is there. Should I uninstall it? 

In my earlier email I gave you the error message when I try to open Word. 
Here's the error message when I try to open Excel:

AppName: excel exe
AppVer: 12.0.6425.1000
AppStamp: 49d6dd6
ModName: olconnector.dll
ModVer: 2.0.3009.0
ModStamp: 4a2e1608
iDebug: 0
Offset: 00011561

Is this also a problem with Outlook Connector? Should I uninstall Microsoft 
Connector? Or, what should I do?

Thanks!

Clarification: I started the last message with "I used Office Diagnostics, 
and all is fine." What I meant is that Office Diagnostics says that all is 
fine. I still have the same problem even after uninstalling Office 2007 and 
then reinstallling it.

Thanks again.
