Modpacks won't open.

[BradleyXD]

Right, so I've been running into an issue ever since I started trying to use the Technic launcher.

I tried getting some modpacks to work and they wouldn't open, my launcher would close but would shortly pop right on up again, and so I thought launching normal tekkit would work and it was just an issue with the packs. But alas, that did not work either.

This has been happening repeatedly, after reinstalling and changing up my settings in every way possible.

Bradley, your video / graphics drivers are out of date. Update it!

Walkthedock, no it is not cool to take someone elses report for your own. Don't do that. Create your own report

Edit. I'll change that last part. Don't post custom pack problems on Bug Reports
