Same issues. Fine last night. Booted up this evening, UPDATES ARE NOT CURRENT. I click to update manually. Nothing happens but for "checking", and then it's right back to "Updates are not current". It doesn't even look for updates. It's immediate. I can click "check for updates" myself over and over and over, and it WILL NOT update at all.
I uninstalled with the mb-clean tool, rebooted, installed new version 3.5.1, as I have done in the past. Same issue. Quit the app, relaunch, same issue.
3.5 on Windows 7 Home does not seem to be able to check for updates AT ALL.
Honestly, this used to be a great program, but lately, it's gotten very buggy and is very annoying as it seems there is always something wrong with it!
