I'm using MultiMC v0.6.2 which just added FTB modpack integration (a nice big step forward, great job). However, the Crash Landing modpack won't run for me, and I don't know why. Every other FTB modpack I've tried works perfectly, altho I haven't tried them all of course. With Crash Landing modpack, the process kills itself within 2 seconds of launch, no Launcher window ever appears.
Is there an issue with amount of RAM allocated in the older modpacks? Naturally I'm using upwards of 12 gigs of RAM for some of the newer packs, so I'm wondering if this might be an issue? I manually set the memory to 4-8 gigs for Crash Landing but maybe even that is too much? Crash Landing is a v1.6.4 modpack, quite old now - is it possible that it won't run on the latest Java update? Could that also be a reason?
Since I don't see any other error reports anywhere, it's probably something on my end, but figured I'd ask about it anyways. I suppose I should also try my old trick and copy the pack over from Twitch manually (it works fine thru the Twitch Launcher but I much prefer to use MultiMC).
