I've had a few crashes when renaming a component. The biggest headache is that not all of the components appear in the library after the crash. Some have disappeared. Running the Re-Index button results in the same situation, crash and Easy-PC shutdown.
As AndyB has already suggested, most likely system is pointing to incorrect library/folder. Check Settings=>Folders=>Libraries where you can see what libraries are listed and enabled.
You say "replacing" your company library, -but not "overwriting" so I suspect both libraries co-exist on your PC which is why the old libraries "return" as the system is probably not pointing to the company libraries you want.
