Download, Launch, Double-Back Issue

[Waterspark357]

I'm having an issue with my modpack (mind this is my first, so these problems are kind of to be expected). It downloads, launches (launcher disappears), and the launcher reappears. I'm using 1.7.2 mods. Copy.com is my download platform. Here's a link to one of my latest error logs:

And here's a link to my modpack:

If you need anymore info, just ask and I'd be glad to help you help me! Thank you for your time and knowledge. ^u^

• This is a (well) known problem when using Forge for 1.7.2 with Java 8. The issue can be fixed by adding Lexmanos' legacy java fixer. That being said, why are you making a 1.7.2 modpack? Nothing is being developed or hardly even maintained for that version anymore.

​Thank you, and 1.7.2 may be less updated, but I've found a lot of useful mods have stopped being updated around that version. This was mainly intended to be a multiplayer modpack, so certain mods can be helpful in these aspect (if not mandatory). But I can see why someone might question that, so you're certainly right to ask that.
