Problems with server patch

[Juno]

Hi, I wanted to test the server so I installed the patch I downloaded from the website and it totally fucked up my Epilogue client.
Now I'm trying to play in another server and I get this error when I run the game "Files are corrupted!!!! Please, full check... [../Sysextures/L2Font-e.utx]"
I don't have a clean copy of the client and I can't run the updater cause it'll update to Freiya so I'm pretty screwd.
Do you have a solution for this?

Thanks.
