this hasn't happened to me, but I worry about, and I get frustrated with PSN's network quite often. I've been downloading a lot of games for a while now, I don't know why, I just adopted digital copies pretty easily, and I might get bitten by it.
I hope your PS3 is okay though. I'm a big fan of the PS2/Gamecube combination too, and I have both still operational here and I still buy Ps2 games. Maybe things have gotten too complicated.....
