problems with models.

In my server, all the players including me dont have running or walking animations. Everyone just kind of levitates around on the ground with no animations. Any idead on how to fix?

First, the help forum is a subforum in this forum, not this forum itself.

Second, what’s your tickrate? If it’s 100, set it to 66 and try again.
Third, are you using custom player models? If so, what happens when you use the default/hl2 ones? (Male 07?)
Fourth, what addons are you running?
Fifth and final, run the steam updater/hldsupdatetool with -verify_all at the end. Sometimes the downloads for certain files can corrupt, resulting in wacky issues like yours.
