I was starting my server like any other day. And when i joined, it said "Server uses different class tables". I as told that i need to update the server's gmod, and I triend the hldsupdate tool, and I suspected it wouldnt work, and it didnt. PLZ HALP MEH!

Run the update with the command line flag: -verify_all

Sometimes files corrupt and the update fails.

If its still not working; delete the clientregistry.blob file and run the update again.
