Tunngle Blocking Internet

[Phobos]

I've reinstalld tunngle a dozen times and restarted etc. but this problem keeps popping up

Basically after tunngle has been running for a few minutes my PC loses connection to all other type of internet including browser and XFIRE. Then my internet doesn't work until I shut off internet AND disable the tunngle adapter in network options. When tunngle runs it blocks all other network traffic. I've been trying to find a solution but the info on their website doesn't really help.

Is there something I can modify in the network settings like this (attached image) that will prevent this annoying issue? Please only ppl who know what they're talking about respond.
