So I have a bit of an oddball problem. I downloaded the Technic launcher the other day, downloaded Tekkit lite with no problems, and tried to join a MP server I was hosting. The server crashed, and I exited the Technic launcher. As an attempt as a bug fix, related to my ISPs use of ipv6, I entered "setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true", found here. When I tried to restart the Technic launcher, it now continually loops a javaw.exe process. The only way I was able to exit it was via the console command "taskkill /F /IM javaw.exe". I did delete all the versions of Java that I had installed, as well as deleting all of my Technic launcher files. Judging from the files I now have in the .technic file, it isn't even reaching the point where it will download all of the launcher files. I did not make any attempt to adjust registry values.
I'll add the logs as a download, here1, here2, here3. Logs are too large to allow me to attach them :(.
