Moved everything from one VPS to another (everything like 16GB) in the right directory I do
"screen -S MCMA mono McMyAdmin.exe"
screen and mono are installed and working

when it tried to start it tried 5 times and fails giving me this error

I have renamed the file "FTB-Beta-A" to "FTB-BETA-A" and it says

Probably Case senstive, but that class def not found means its either missing a mod, or you have a client side mod on the server.

I don't understand how that can be, I downloaded the entire mcmyadmin folder with the minceraft folder in it and reuploaded to this new server, I have made no changes.

-edit- I have deleted every mod and core mod and ftbserver.jar (renamed to FTB-Beta-A.jar) reuploaded a new copy of them all from the feedthebeast server download folder and it still doesn't work

Does McMyAdmin run by itself? Also just copy/pasting still changes every file. The directory for it might not be the same and that can throw it off also (if its not using local tree)

Did you rename anything?

Also try just running the server not threw mcmyadmin and see if it will start.

I have not renamed anything but i've only used mcmyadmin to start the server before so how would I start it without it?
