Error in Metadata manager when trying to open calculations

Having an issue when I try to open the calculations tab in BIDS against an OLAP database or a MSAS project. BIDS hangs for a second than comes back with an "unexpected errror" in the middle of the screen and then shuts down. If I check the event viewer I get

Errors in the metadata manager. The configuration property updates were not persisted. Internal error: An unexpected exception occured

I can access every other tab in the project, just not the calculations tab.

Anyone run into this before?

Thanks

FJK,

I think I read some time ago that you could get this message if you have different msolap90.dll installed on your PC in different folders. Could you search for this dll on your PC and if different version found, try to replace dll to match.
