Have you tried logged in as a different user on the local workstation? You might need to delete (after backing up first just to make sure) the registry keys:
HKCU\Software\Solidworks..... and do a complete re-install. Also it might be worth deleteing your local EPDM cache????
Im not expert but thought Id try and offer up some solutions for a change.
I was not sure about the key to delete., so I got wrong...
Finally restore my system to previous point and reinstall everything.
Then it Works!
Still don't know what happens, thank you anyway.
