HELP: Decompression error

[Jaquet]

The server I work for, Zana, has this problem where when you try looking at the levels by clicking the levels folder on RC and a Decompression Error msg pops up and we cant access our levels and we cant log onto Zana anymore. We cant figure out how to fix this and so we need a global who can log on and maybe try to fix it i guess. Its been like this for about a week now. Someone please help? lordVyse tried helping but he couldnt figure it out either.
