Nevermind, found the issues. It seems there are servers giving bad texture files (wrong size) and cause black and pink texture squares, if you delete them and re-download them (at least from my server) everything works just fine!

Sorry for the post.

Check download list. Otherwise check Adding Models (6.1.2) in manual.

I had checked that, everything was just fine. I edited my post. The problem lays on servers giving you corrupted files and then joining another server with the same name textures. I deleted them from my steam account and re-downloaded them from my own server, and they worked perfectly!
