Muse crashes when using Save or "Save as"

I just tried to open an existing file from the previous version.

Made changes and published.

>save as

Error message that occurred:

Adobe Muse CC has encountered an error and will now exit.

Please report the last few actions you took leading up to this

error to the Adobe Muse CC Team.

Unowned UID in database. UID: U1065

Class: BitmapObject persistOwner:non-existent uid:1063

Not sure whats going on here because it lets me save other files created on the

new version, but gives me this when I try to save files created in previous version.

Any help out there?

Thanks
