My client doesn't want to launch Forge 1.8 and its REALLY annoying. If someone would PLEASE look at this and help with a fix that would be so awesome. I'm have v1.8 an for Minecraft and Forge and I also have Java 7 but I have no idea what's wrong.

Your mod installation is wrong.

Thanks. So should I delete all Forge versions/profile and redo the whole installation process?

Yep I did all that and it is working now. Thanks a lot.
