Popsloader confusion/More Info needed?

[FenrirX]

So... I threw Popsloader onto my PSP and I turned on the plug in in Recovery
- I also decrypted the PRX files from a firmware file, but when i try to run my Final Fantasy Tactics it doesn't even attempt to run the Eboot, or give me the Popsloader menu. Just gives me an error that the file is corrupt. This Eboot worked on 2.60OE No Problem...Any help would be outstanding
