I have a little problem too

I used Memory Browser to find and decode pw and it seems to be correct so i'm happy xD
but.. i can't open .pk files by this key.
It's working perfect with clean engine etc. but when it's uptaded (another pw of course) it doesn't work ;/
I think the reason is a KOCP but i don't know what i need to do with this..
Really thx if someone can help me a little xD
Sry for my english ;]
