Custom Modpack causes Gray Screen

[grrxmaster]

After messing about trying to make a custom modpack, I've almost got it (I believe). Unfortunately, now when I attempt to launch the modpack, it appears to unpack the mods, and forge initializes, but after the Mojang screen flashes the screen merely becomes a gray screen, with no error messages. Any help with this would be lovely. I'll add some links.

Closing thread, someone solved the problem. There was an issue with Modular Powersuits and Mekanism.

I have the same problem, do you know what they did to solve it?

I looked at both modular powersuits and mekanism, but I didn't see any item ID conflicts. Looking in the Forge logs I don't see any errors (though granted I'm rather new at this), and the server with all the same mods starts without any problems. It's just that the client goes right to a grey screen and I can't figure out what's wrong.

You got the grey screen because of some conflict between mods.
