Stuck with a server loader

i downloaded beam mp and started a server just to join my friend but we eneded up just deleting beam mp all together but even when i load the game from steam with the beam mp file gone and he game newly installed no matter what map i run i always get the content from the server stuck to my game which includes a custom loading screen with rediculous horrible music, custom unwanted vehicles and a user agreement menu every time i load up. i hate it but ive looked everywhere for the file and i cant find it to destroy it. i want my normal beam ng drive back. i need help .
