3.72 POPS won't work

I dumped the files using PSAR dumper (new version), renamed the files to 372 after the names, and put thm all in the correct place. Yet, for some reason, whenever I select this in the popsloader menu, it just freezes and I have to shut off my PSP. All the other POPS work perfectly fine, yet 3.72 ain't working for me. I've only tried one game (FF chronicles, the FFIV disc), so I don't know if that would affect anything. Anyone?

EDIT: Sorry, double posted thread. Accident I swear.

Anyone???
