Strange Newgen Problem

[shinami]

K, so i formated my pc recently and i installed wc3. Then i installed newgen did all the stuff to make it work on 1.22. Launched it. Activated UMSWE. Restarted. Then when i try to set the map size W:480 H:480, either H or W gets automaticly set to 128. Anyone knows what might be the problem?

EDIT: Nvm i'm an idiot, forgot to turn on no limits
