Hi everyone. I got the same error (8002AE04) trying to install three new demos from the US store (Narnia, Wall-e and Monster Madness).
I'm from Europe, so I can't download them from the shop directly, because we don't have good demos.
I tried the PS3 Proxy method like always, but with these three demos it did not work. I never had problems before installing demos this way (before with F@H and now with the pause download trick from the store). Downloading them to the PS3 was no problem, and I still have them in Games, but just can't install them.
Is it possible that the problem came with the new firmware? I've updated to 2.41 before trying to install these demos.
I have not tried older demos that worked before though. I might download an older demo which I have played already, but I have a slow connection, so it might take a while to download.
Thanks for any help. I hope Sony did not "fix" this, can't imagine a future with only demons from the crappy euro shop ...
