When I bought my PSP, it was a version 2.81. I couldn't play any homebrewed games, so I tried to upgrade it to 3.10 and install the 3.10 OE-A patch by Dark Alex. However, when I tried to run the 3.10 OE-A installer, I got a message "The game could not be started (8002014C). I though no big deal, and upgraded to 3.40 and tried to run 3.40 OE-A installer. Once again, I got the 8002014C error. I could successfully run the official updaters, and can run UMDs just fine. If anybody knows how to fix this problem, please help me!
