Forge!
So, I got Minecraft forge for 1.7.2 and a bunch of mods. Forge and my mods always worked for me. So I got this new mod today, and when I launched Minecraft on my Forge Profile and pressed play and Minecraft never popped up afterwards. So I deleted my .minecraft folder and got Minecraft and forge again. But it still never showed up! And so I tried to try vanilla Minecraft and it worked fine. I have 3 Minecraft shortcuts. So, I don't know why forge isn't working for me! Can you tell me what I can do? And no, I did not receive a crash report.
P.S : I can't live without mods.

Ok, having had a look at the error log, the issue is forge having problems with java 8. You'll either need to set your minecraft to run with Java 7 to solve the issue, or upgrade your forge version to build 1217 or above.
Go to your forge profile in the launcher, click edit profile, then tick the launcher visibility checkbox and change the option dropdown to keep launcher open, then save the profile. This will keep your launcher open when your forge install starts, and show the game output in a tab on the launcher. There will hopefully be an error report or crash message in that game output, reply or edit your above post with it in (Use a spoiler If it's long) Should provide some pointers as to what the problem is.

Couple of questions just to clarify, when you re-installed minecraft and forge, did you put the same mods back in and get the problem, or not put any mods in at all? And secondly does your minecraft launcher dissapear after you press play, and then nothing happens? Given what you've said, the problem is most likely a case of your new mod having compatibility issues with one or more of the other mods in your install.
I did not put any mods in at all, and yes, it does disappear after I press play.
