Minecraft wont start

[destroyerwilly]

so i reinstalled forge (Installer version) for 1.6.4 but every time i start the launcher and push play the screen disappears for a second then comes back it happens every time i have no idea what to do about it, it can be that no mod will work on 1.6 would i would like a dev to help me with that too, or there is a problem with the FML anyways please help me with that

I am no expert with this at all but I have a few suggestions to try.

 

1. Re install forge

 

2. Try not to use dev. They are more for developers for servers.

 

3. Something may be incompatible. 1 can throw the whole thing off. Check your mods.

 

 

More info would be great.
