Hi bbarbour
I have tried to recreate your scenario and have not been abled
to reproduce the error that you describe. This must mean that I am either not
reproducing the steps correctly or there may be something specifically wrong
with either your workflow or your setup.
Can you open any of the lower level files?
What error message do you get?
Were you doing this remotely over a network?
If working in a multi user environment did you have all the
files checked out to you?
Can you provide me with some or all of your files to have
a look at in a pre crash state (ie before you renamed\relocated them in DA).
Preferably with the main assy, and some parts with derived parts
inserted.
I can provide details of a secure ftp where you can upload
them.
