Launch Issues

[The Damned]

I've downloaded FTB several times and updated it everytime but for some reason every time I launch it, it gets to the point where it says it's launching minecraft then it quits and the error message:

Launching with applet wrapper...

Can anyone help me fix this problem?

Start with the above posted instructions.

Since what you've provided is very little help, I am going to assume you're using Java 7, while you should be using Java 6. (This is the most common issue with Mac users when trying to use the launcher)
