I have a project that the editors cannot make a new bin in the project window.  They keep getting a access violation error.  But the rooms have full read/write access to the workspaces.

Any thoughts?

 First, try deleting the "(Project name)settings.avs" file. It may have become corrupted. If that doesn't work, try deleting and rebuilding site settings files: MC State, Site_Settings, Site_Attributes. In both cases, on re-launch the system will detect the missing files and build new ones.

Got it, thanks for the help.
