Shader not files found

[duster]

Hi.I started playng JKA again and i'm playng in my friend's server but sometimes it crashes and i get the following error:

 

149817 files in pk3 files
Shutting down OpenGL subsystem
ERROR: no shader files found

 

It doesn't happen every time i try to join and it's random but other servers go alright.Another friend has the same problems sometimes with other servers.And i tryed to play without any mods so i am pretty sure that a mod wouldn't be the problem.

Does someone know why this is happening?Thank's in advance!

 

Edit:I think that i solved the issue by deleting the folder that the server had created in my GameData folder.

I suggest you shoot yourself in the face.
