Cant Open Tekkit Classic on New Launcher (on Windows 8)

[jrblaisse]

I recently upgraded my computer to Windows 8 which has been out for months now, as well as updating to the new technic launcher which came out only a short while ago. I want to open tekkit CLASSIC, and was able to before all my updating, but no am unable to. PLEASE HELP!! Ive already updated my Java to the most recent version and every time I try to launch Tekkit Classic, I always stop at the same place (on the console log that is, posted below (focusing on where it stops loading at the bottom of the thread list there)) and the launcher loading bar at exactly 50%. However sometimes it says "100% No Tekkit update found". Ive almost given up hope on this one guys, I am desperate at this point. Again, I know its not my Java or Firewall so yeah...

Again, like clockwork, it always just stops loading at the same exact point in the console (at java.net.URLClassLoader.findClass(Unknown Source)

Try resetting Tekkit Classic's files. This will reset the modpack.jar and minecraft.jar of the pack, possibly fixing whatever the problem is.

To do this, open the launcher, hit the cog below the Tekkit Classic pack, and select "Reset Pack". Then log in as you normally would. If all else fails, try reinstalling the launcher.
