Modpack Not Loading

[ThatRandom]

Hello all,

 

I just recently decided to upgrade from the old Technic I had (Last release of SSP, I think?) so I deleted all the old files, re-installed the launcher, etc, etc.

 

After browsing for a bit I decided on the pack Treeit (http://www.technicpack.net/modpack/details/treeit.24986 for the details, if that helps)

 

Downloaded it relatively smoothly, however it won't start up whatsoever. Vanilla Minecraft starts up, I haven't downloaded any of the other packs because my internet is terrible. All I get is the launcher being 'hidden' (which means it's trying) but no game pops up - the launcher just reappears in a few seconds. I have the RAM set to 2GB, and I've looked at the console but I honestly have no idea what to look at.

 

Platform ID is here: http://www.technicpack.net/api/modpack/treeit

 

If anyone could give me suggestions as to what exactly is causing the problem, refer me to another post on the same topic, or give me guidance in really any way that'd be great. 

 

 

(Also, I don't know where I should be lifting an error log to post from, so if that's required and you could let me know that'd help. My Technic is on the default folder location)
