Castillo, be kind. He does not know anything about scripting and your res title sounds like what you call a "magic script".
You should have called your resource "EXP Manager".
Maybe it's just Castillo's bad script
Or 1.1.1 updates made it be wrong.
But by you, there is nothing to do. You should try to learn how to script instead of using community script. Those servers based on community never get far.
No. Join your server, login as admin, and write it.
Then, here, you must report what does it say (say whole lines please, not something like "there is an error of guigetsize").
If nothing happens, restart the script.
You know what. It's very wrong from you to use dxText for this. You should use your own onClientRender script. It's much easier and less CPU using than this. This system was made for other kind of purposes.
IDK. Maybe there are too much objects on the maps you play. Have you tried playing Xzibit's Skilled Infernus, for example? Maybe it's the decoration abuse what makes your game slower.
