Upgrade to 968 problem

I just upgraded my developer edition to version 968 and now I am unable to import any of my exisiting BSV versions.

I also had a version under test that had not been loaded that was removed from the configuration tool when I attempted to load the version.

Any thoughts on what I may have done?

The error I get is "Exception changing status of the business space version Internal system error. Null"

I apologize. The app that I was having issue with is a very large app. I adjusted my memory settings and everything was fine.
