Hello. I am currently having problems with my PSP with 5.50 Gen-D3 With Prometheus 4.

My Problem is that it just does not work. When I try to boot up a game like Peace Walker, It just says my version is 5.50, and that I need to update. This is very odd, Because I had it working on my PSP before, but then I decided to format my Memory stick, and re-install everything. If you guys could Help me with this that would be appecieated.

My PSP specs in case you need them:
PSP 1000
Motherboard TA-082
I have to use a Magic Memory stick and Pandora Battery because They are the only things I have (Will boot without them though).
