Well I am having sort of the same trouble as HOG - all the packs are on my PSP and visible at the Save Data Utility, but when I try to start Pure, my PSP crashes! or rather, freezes - right at the first Pure loading screen, while the psp is accessing the memory stick. AARRGH! I've had no problems with my cheapo memory stick prior to this so must have done something...dumb.

(Probably that I downloaded the rar files to my PC and then used winRAR to export them to the PSP via USB cable. Do I have to download using the UMD?)
