My modpacks aren't working!

[Apputnins]

So, i was checking out my modpacks, and i wanted to check out TPPI, but it started and then disapeared. No crash message, no nothing. I tried to use other modpacks, but they also opened, and then closed.

Can someone help me?

@xtremehunter15: Posting in multiple threads for the same problem is considered bad form.

 

Technical problems with the default packs should be in their respective Trackers (top of this page). Make sure you are not using Java 8.
