I just uninstalled PeerBlock yesterday, and hadn't had it running for over 2 months. Hamachi works fine on my friend's PC with Tunngle, but I closed it & disabled the service anyway. Problem not solved.
I downloaded the installer yesterday, and even made it check for updates on installation. I tried a full uninstall, reboot, install, reboot, and it didn't work, then I tried the community troubleshooter.
It doesn't open any GUI whatsoever. As soon as I click to open it, the first error box pops up. Then, about 10 seconds later (after clicking OK on the first one), the second one pops up. After clicking okay on that, nothing happens. Tunngle doesn't start. :C
