Redownloading the game?

All you had to do was put teh steamapps folder back, then right click the game in your library, click "properties", go to the "local files" tab, click "verify integrity of game cache", wait for it to finish.

none of that was changed, i left it all alone so that way nothing could get messed up

IIRC, Steam looks at AppUpdateStats.blob to see how much of the game has been downloaded. Verifying cache is supposed to check the game files and compare to how much the blob file has recorded, along with what files are indicated by the NCF, GCF, or ACF files (not sure on ACF, since it uses a new format and I'm not aware of any 3rd party tools that can read it). If you manually copied the game over (say from a retail disk, but later rebought the game on Steam), you verify the cache so it doesn't redownload the entire thing, only the files that are missing.

Since your blob files are gone, steam doesn't know which game is installed and how much has been downloaded

I could be wrong and thinking about the wrong blob file though.

If all that changed is the internet connection, try another game. If that still doesnt work, see if your new modem/router has a firewall. You'd also get a new IP, which may cause Windows firewall to not have the same rules.

I checked a few games, only game that worked was a game that wasn't on the steam account. I'll know tomorrow if I still have trouble with the games on steam.

re-installing steam seams to have fixed the problem
