Revit 2015 crashes won't syncronize

[Anonymous]

My Central project synced fine when I left last night. Someone came in about an hour later and opened the file and when the person synced to central he got a fatal error and asked to Recover. It did NOT create a recovery file and shut down. He detached the file then tried to recreate and save as a new central model. Same error. Today we tried to detatch from Central and it worked fine, BUT when we tried to activate worksets to allow creation of a new central model it gets to 22% then same Unrecoverable error. We have not lost any work done on the file working as a detatched file, but a bit of a pain not being able to have 2 guys working on it. Any ideas??

Did you ever get this problem fixed? We seem to have the same issue going on in our office...

Thanks

Yes we did after much diliberation between us, our supplier and Autodesk. Make sure ALL and I mean ALL of your Revit installations are the same build number and the same Revision number. we had to go to Rev 10. After that it seemed to work. Might be different issue if this doesn't work for you.
