When joining a server, no cars spawned and can't spawn own car

Always when I try to join a server, there are players, but no players have spawned cars, but the names are there, like they have cars. When I use the node grabber, I can see the JBeams, so, that means, people have cars spawned. When I try to spawn a car, no car appears (probally only the JBeam is there).
It was okay before, but now I have this problem. (Sometimes appears the error “didn’t receive any mods” and “connection terminated”, but the problem is the same.) I need help, please!
(I moved the location of game to the BeamMP Launcher Folder before, if I reset the location, I see other players, but when I spawn a car, the game crashes. When I move it back, I can’t see players then.)
