I've got my psp slim running 5.02 gen-a (full). i edited the vsh text so i can access the playstation store via media go. whenever i download a theme or video, it works fine. However, if i attempt to download a demo for a game it dosent work. The psp stops showing data transfer about 5 sec in. Once media go says download complete i try to start up the game. I get an error taht says the game could not be started then it gives me error code 80010013. Anything i should do to fix? this has happened to more than one demo and it makes me reluctant to purchase anything from the store.

I think you have to go into recovery mode and disable your game plugins, I've come across this before in M33.
