Things got really messy now...
I was working on cloning BSP in my PB4.1 and I just went to
File/Manage Catalog Features to remove my new BSP from Catalog.
When I clocked "remove" button on this window PB crashed.
Now I am not able to start PB at all. It fails with a message
"Unable to initialize Catalog" followed by the "Runtime error"
window and cepb.exe crashes. What can I do to avoid reinstallation?
