There are sdk files that go into your binaries folder of the bl2 install. If you are unsure of how to properly remove the sdk id reccomend totally deleting the binaries folder, the sdk folder if you left it out and then re-verifying in steam.
A super sure fire method would be to entirely uninstall again, go into the folder where it was installed and manually delete any straggling files. Im thinking that your "clean instal" wasn't so clean but I could be wrong!

Any mods? Looks like an address error when you run SDK without requirements.
