OK, I have just managed to get PES2011 patched. I really didn't want to do it the slow way, so I tried FTPing to various locations, editing files with PARAM edit to make them compatible with my account etc. But eventually I gave up and did the manual copy. Took about 40 minutes, but it seemed longer! But my advice would be to just persevere, it's worth it!
Also worth mentioning that even the manual copy wouldn't work until I was able to get connected to PSN and update the game to the latest version. So get the update while PSN is still accessible!
