I don't know why the op might have been having problems for such a long time, but I know Steam was having a few issues earlier today.
Earlier I got a message that one of my other games wasn't available, please try again later, so there might be problems with heavy traffic today.
Not everything is automatically piracy people. Accusations like that aren't really a good thing, m'kay?
My posts were apparently too subtle in the sarcastic department to be detected.
You see Talaran, we never had these problems with Bethesda games in the past. Don't get me wrong, I love steam, but there's no reason it has to be intertwined to such an extent for people who bought retail copies. Historically, Bethesda has had thing called common sense that they seemingly used to publish games: They didn't use any draconian DRM that prevented people from playing the game they bought, just CD checks at worst. The reason it's common sense is because the DRM doesn't work, at all, period. With requiring Steam, it's a step in the wrong direction especially when people who bought it can't play it without steam, unless steam gets it's act together and adds "once per computer activiation", which I have no problem with. Therefore, bethesda, through steam, thought the OP was a pirate by not allowing them to play their own game without the DRM validation. The game was there, the files were there, but Bethesda was keeping the OP at the "you dirty pirate" gate until proven innocent.
