I've tried to run the GTA-LCS Hello World app and am experiencing the same problem as several other ppl in the forums (after activating the Hello World savegame file, it shuts down the PSP while loading). Before someone rants that I'm doing it wrong or calls me a noob I can assure u I have tried every tip "I've seen" in the forums to no avail. Technically, I'm fairly experienced at downgrading and running homebrew on PSP's and as such I am absolutely certain that I've installed it correctly.
Any Ideas

Spec : 2.5 Gigapack & GTA-LCS euro
