I'm on a rooted stock 2.1 (not a custom rom). As of last night, I am unable to download from the market. I have tried signing out/in to google talk, clearing cache and data on a lot of the apps such as market, downloader, google aps, etc. I have rebooted phone. I have uninstalled apps to make sure there's room. I have tried on both 3g and wifi. I'm not sure what's left to try, but I can't get any downloads to work and I'm out of ideas.
