I am trying to set up a redirect server for UT99.
The game server is running fine and all are able to download the necessary files as long as they are not compressed.
The problem is that when I add any .uz files to the ftp redirect server and someone tries to download a file they do not already have, the following error message appears on the screen:

The game crashes before this message appears, and it doesn't matter what type of .uz file was being downloaded by the player, whether a map.unr.uz or a mutator.u.uz or mutator.int.uz, etc.
The download from the redirect actually gets to the end of the file the player is attempting to download and then the game crashes out to their desktop, and the error message is displayed
If anyone can help us to correct this problem and describe the cause we would greatly appreciate it.
Happy Fraggin'
