hope dis will help you

Hi, so lately, I've been trying to play on the server, which worked pretty well.. for some time. I can play some time, but then (usually after about 1 minute of playing), I get a gravity error.
Does anybody know how to fix this problem?
I'd really appreciate some help ._.

Thanks,
Munchie.
