I prefer to utilize Java 6, and my computer employs Windows 7.
I have been having the same problem with Technic, Yog, Tekkit Classic, and Hack/Mine, however not with Lite, or Volt, and only once did Technic work, but it was when only about 6 mods had loaded, as I had seen from my game console. Though when I tried removal of all Technic mods and then playing, no success, an error message, and it didn't even attain the Mojang screen.
My errors have occured since 1.1.2, and I wish I could know what has changed between 1.1.1 and 1.1.2, and if there might be a fix/way to revert to 1.1.1.
