OK, I think I'm going to have to ditch Check for Updates. Reloading the addon manually worked when it was one file but it isn't reliable with a whole folder of them.

No, wait. Damn I'm derp. It's still using the 2.0.3 or whatever when I launch it, and when I try to install 2.1... This happens [sta.sh]. If I use "Check for Updates", it does that "only Export button is there" thing, but not red, just normally gray.

I can't be more specific. I installed Blender 2.70a, imported "previous settings" when I launched it, and then the Source Engine Export thing just showed 1 red Export button and the Check for Updates button, nothing else. The other 2 Source Engine tab things were completely empty. I "checked for updates", and then it all just errored out, and the Source Tools disabled themselves, having me unable to turn them on. Even after removing them and installing them via the zip download. But now, it mysteriously works again.

Like Vossie said. It flubbed up there. So I removed it and re downloaded on my own. Worked for my other friend though.

The Check for updates-button doesn't download the update correctly.

Everything works fine for me. Please be more specific.

It doesn't seem to like Blender 2.70a...
