AAF Spellcheck crashing word

Hi,

We recently migrated a client to a new server and since the migration the AAFSpellcheck function crashes Winword.exe. I don't really think this is a Windev issue but I'm hoping that it's maybe something someone have seen before and can offer some guidance.

We get an error that says:
This feature is not available Word is not installed properly on this computer.
Access to Selection Autmoation member
Error 800706BA

Problem signature:
Problem Event Name: APPCRASH
Application Name: WINWORD.EXE
Application Version: 15.0.4893.1000
Application Timestamp: 584f9853
Fault Module Name: wwlib.dll

Any advice would be greatly appreciated.

Thanks!
