Need help regarding CWCheat

[opiosama]

i've been using CWCheat for some time in MHF2 without problems for some time now..however a few moments ago,i activated the cheat menu with select and my psp hanged.i took out the battery,rebooted my psp while holding R,but it shows a black screen..and when i reboot without holding R,my psp starts up normally..

is there something wrong with my CWCheat?i tried deleting the folder(seplugins) and moving a fresh one into my memory stick root but still same problem..why is there a black screen now,instead of the usual teal background menu when booting up..thanks in advance for any help.
