So, in my last ditch attempt to get on steam, I somehow unproperly uninstalled it. I used the steam uninstall, and the HL2 CD said it was still on. I deleted everything I could find with search that seemed like it was actually a part of steam, and I deleted all the stuff under steam in the registry. Still no dice. I just wanted to reinstall it so I could have half a chance of updating it.
Is there any way besides a reformat that could remove all traces of steam?
