I am assuming you installed microb, if you did, there should be a new entry on the menu in your browser, called 'hidden' i think, it should give you options to switch between the different engines. I would try just removing what you installed first and see if that fixes it, just so you know there is a microb for OS 2006 for the 770 if you used the repo i don't see how(unless you are in red pill mode) you could install the wrong version. If this did not help get back to us with a little more info, good luck.
