Hello. I recently made a custom modpack for myself and a few friends. Up until today, it was working fine for everyone, and it was a blast. However, one person is now unable to launch the pack from the Technic Launcher, and I can't make heads or tails of it. When he goes to launch the pack, the launcher hides, then shortly pops back up. It was working just fine last night. Hopefully, someone here can shed some light on the issue. I, myself, and one other person can launch the pack with no issue. I've launched the pack with Java 7 and 8 with no issue. The pack was made for 1.7.10. The api link is here http://api.technicpack.net/modpack/atmosfear-pack and the log from his client is here http://pastebin.com/RVv62NQR . I appreciate any and all help with this. If there's anything I left out, I'll try to get it added in as soon as I possibly can. Thanks again!
