Strange, is there anything unusual about your Documents directory path? Is it redirected to a network share or have a quota that would be causing a failure to write or read files there?
Can you post the exact error message? That might provide a clue for what's going wrong here.
No there is nothing unusual about my setup. Everything on C Drive, auto installed wherever it would naturally go.
However once I restarted everything to write down the error, It seemed to load up fine. So I'm not sure what changed.
Darn, I never like to have a bug get away, but I'm glad it worked itself out.
One possible explanation is that a search or other indexer had a lock on one of the files that caused a failure during the copying or loading of the copied project. I have a script for simulating such conditions and may try to recreate your error based on that hypothesis.
Thanks for taking the time to report and of course if you see it (or any other issues) again, definitely pass them along.
Thanks! -- Dan Tull
Depending on the type of error, clicking the refresh button (two arrows pointing at each other in the bottom right corner of the scene panel) may get you past it.
