Minecraft not loading after hitting play

I was playing minecraft today for like 2 hours, whilst recording, all was fine and dandy

I logged off and closed game to edit and upload

I just tried to log back on and after loading the launcher, and hitting play on my Forge profile (the one I always use and was working fine an hour before) the green bar loaded 100% my mouse had a quick load symbol, but then nothing happened. No game opening, nothing.

I saved my saves file, my mods and my resource packs and deleted .minecraft and opened the minecraft launcher once again to reinstall everything.

It worked, minecraft then loaded into the game, I backed out to reinstall forge and my mods / resource packs.

When loaded back in, I chose my Forge profile again and the same issue as above happened yet again. I have no clue why it is doing it as I literally played an hour before and nothing changed since.

I am on 1.7.10 minecraft and forge version forge-1.7.10-10.13.0.1208-installer

I also tried the forge-1.7.10-10.13.0.1187-installer version too, with the same issues once again.

Whats happened? Any ideas? Thanks
