What's the issue you encountered?

Inserted Biomes O Plenty and Terrablender in mod folder, tried to open up game, got Exit Code -1 and cannot enter the game.
I also have several mods downloaded which may be the cause for this. I will list if required.

How can the issue be reproduced?

Attempting to enter game.
