"Failed to connect to hamachi servers"

One day Hamachi just started giving me this error message. After browsing many threads this is my last effort to make it work.
Things I've tried:
Services.msc disabling tunnel engine and deleting folder contents and re enabling tunnel engine.
Changing port number of Server address from 12975 to 12976
Uninstalling and reinstalling
Other things that I can't think of right now. Any help would be greatly appreciated, thanks.
