It Was No Help At All

The “Oops…” error: The list of things to try, given in the Blizzard text on this subject, talks about proxies (whatever that is) and things that I already tried - that didn’t work. I’m getting the “Oops …” error for Repair and for Uninstall\Reinstall. I’m not a computer tech and don’t know tech language. I’m just a gamer without my game.

Please help.
