GUI XML error - Check UIErrors file

[Pixal]

I downloaded everything and followed all the directions closely.

However, after I log in and select the Project 1999 server and push play, it goes black for a bit then crashes and gives me this error message:

GUI XML error - Check UIErrors.txt file

I rechecked the patch files, including the new one from yesterday. I rechecked all the little things I was asked to change. not sure what I am doing wrong.

Help?
