My modpack won't launch

[frsr15]

Whenever i try and launch my modpack, it will download everything and then the launcher will crash and load again. Minecraft wont come up. I thought it was something to do with a mod so i deleted spacecore... and minecraft finally launched! But when it loaded it said that it couldn't find spacecore! But that always makes it so i cant open the pack. Can any one help?

The error in that log indicates a problem with IDFixMinus. However, without a link to your pack page or download it is impossible to debug.
