I don't even know where to start. Anyone knows common reasons?

 

Why? I just updated to latest 1.8, fixed my code and this thing happens. (yes, I know how to setup forge)

1.7.10 is no longer supported by forge, you are on your own.

In 1.8, the tweakClass as well as everything else to do with cpw.mods was changed to net.minecraftforge, that was your problem is upon launch you never changed the tweak class
