I recently had to re-install Windows and thus Minecraft.  I installed the most recent version of Minecraft Launcher 1.6.11 from their homepage.  Then installed the latest version of Forge.  After setting up my profile, using 1.7.2 Forge and only that version's mods, the game will not load.  I am able to run non-forge versions with no issues.  I also have the latest Java 8 installed.  Please advise.
