NEVERMIND, I fixed it. My Java wasn't updated. ^^;
For the past few days, I've been trying to get technic launcher to run.
Normally with my computer, it would show the logo for a few seconds--then the launcher would appear. But when I tried to load the launcher a few days ago; nothing happened. The logo didn't pop up, nor did the launcher. It has been a while since I've used the launcher, but I'm not sure if that would contribute to this issue.
I tried unistalling the launcher, but when I did so the .technic folder in "Roaming" disappeared; then it wouldn't re-appear when I installed the launcher again.
I don't know why this is happening, does anyone else know?
