Once 2.0.0 was released all auto-update issues have been resolved. I have not had any reports of issues since. Are you using a BETA version? That may still cause an issue. You can re-download from the 2.0.0 link you were emailed to get the latest version. When you install completely remove the existing install just to make sure and clear out anything that might causing the issue to fail going forward. This is a good idea if you ever use a non-official release as well.
