Launcher Closes instead of Launching Minecraft

[Nhawks17]

Yes i know i know this isn't the right place to put this, i apparently don"t have permission to post in the technical support section so i cant put it there! Anyways, so like the title says I try to launch FTB and when it does the launcher closes, the console stays up, and minecraft does not open. I have updated Java to the latest, re installed FTB moved the directory to appdata, all that jazz and still nothing works? Any ideas on a fix, or is this something the developers need to fix? Let me know if you can help please dont just comment complaining i put it in the wrong spot

(Screenshot of what happens)(And my processes running, looks like its running but not showing up?)

Oh and here is my log:

Also for the record, the FTB Launcher doesn't like it when you set the max RAM to above 1 gigabyte. No idea why. But changing it down seems to fix it.
