Custom Modpack wont start up

[dbrown1111]

I made a modpack and every time I try to start it the launcher disappears and re-appears. Can someone help me

Forge swallowed something bad, probably a dev version, bad or corrupted mod.

 

Where did you get those mods from? 9minecraft? Those don't look like the official versions.

 

There are safer places to download mods: curse, curseforge, minecraftforum.

 

Replace the mods with their proper versions and recheck.

• Your modpack is configured to be for MC 1.8.1 on the settings page. You need to select 1.7.10.
• All of your mods are from illegitimate sources. This post on getting mods may help you:
