Okay so forge is properly installed and starts up the game now however it will not load any mod I use not even the smallest of mods and I don't know why since I'm still new to all this. I tried on another computer with the buildcraft mod and it works fine there. I'm not sure what is going wrong so any help would be liked very much. I've no info I can add as nothing crashes it just doesn't load anything.
My computer is a Toshiba satelite with 4 gig ram memory same as my dad's toshiba. His is newer though. The buildcraft mod doesn't require even half of that in space so it should work fine however forge doesn't seem to do anything with any of the mods I put in the mods file.
