stuck at 3.52 M33

[kelidus]

So I finally modded my PSP and got 3.52 M33 running on it. Problem is I can't upgrade to 3.90 M33 unless I have 3.52 M33-3, and apparently I have the release version. Bigger problem is no matter what I try to upgrade to (52-3, 71, etc) it ALWAYS says "The game could not be started (80020148)" Only time it doesn't say this is when I tried to upgrade to the 3.90 M33 and it just told me I didn't have 3.52 M33-3.

Can anyone help me get past this? I've tried just about all the firmware upgrades on Dark Alex's site and nothing seems to want to work.
