[Win7/64] When I try to mail merge in Word 2010 and use Outlook Contacts, Word crashes most of the time. It crashes with letter, emails, labels, envelopes and directory. Here's one of the examples of problem details I get:

Problem signature:
Problem Event Name: APPCRASH
Application Name: WINWORD.EXE
Application Version: 14.0.5123.5000
Application Timestamp: 4c646b38
Fault Module Name: mspst32.dll
Fault Module Version: 14.0.4760.1000

Exception Code: c0000005
Exception Offset: 0003b8f9

The fault module seems to change with the different choices. The above was for letter. Here's the problem details for labels:

A different fault module.

Most of the experts consulted suggested running Word in safe mode as a test. It crashed twice, once in labels with

Problem signature:
Problem Event Name: APPCRASH
Application Name: WINWORD.EXE
Application Version: 14.0.5123.5000
Application Timestamp: 4c646b38

Exception Offset: 0003b8f9

And once in "directory" with the problem details:

Problem signature:

Since is crashes in SAFE MODE as well as regular mode, I'm assuming it's not an add-in that causing the problem. I also ran Outlook in safe, tried to mailmerge in Word and word still crashed. I ran both programs in safe mode and Word still crashed repeatedly in mailmerge with the same problem details above.

Anyone help with this problem, please.

Thanks.
