I don't even get that, just a blank screen :( edit: It seems to be working now. I think I needed to go verify my email first. If you are also a new Steam user trying to download portal, go check your inbox first.
Steam is being a huge pain so far. I was downloading portal and it crashed. I relaunched it but it didn't resume downloading, yet I couldn't play the game, and didn't find a way to restart the download. Ended up deleting the whole thing and I'm now trying again from the start... sigh edit: Great, I re-installed but it still lists Portal in my "library", and I don't see any way to re-download it or delete it or anythi…
Also, if you right-click on the game in your Library, and then select "Properties," there's a "Local Files" tab which lets you delete the local cache, and verify that everything's there. Hopefully one of those will make it realize the download didn't finish.
