Vividan RPG client right? If it didn't go away after erasing add-on, you must delete cache.db most likely
Cache.db is more about files downloaded from the server.
So i noticed after i installed a client for a magic server that i used to play on i wasn't able to do anything that involved crouching at the same time.
In the client Shift+Jet and Shift+Jump were both used to activate different types of magic so i thought deleting the client would solve my problems but it hasn't. Is there anyway i can fix it?
Try re-binding your keys, it's likely that they are still bound even though they are gone.
Go to options, controls, and click the defaults or what ever it is, been a while since I've been in options.
