Another silly question...
I have a saved game w/ my fighter and 6 other characters (Anomen, Minsc, Jaheira, Aerie and yoshimo). All are in that 2.95 million exp where they can't go any further. I applied the exp. cap off thing and I still can't get anything further.

Do I have to restart again to have it work?

Make sure that you installed the exp cap removing feature into the override folder!
It is important else it doesn't work at all.

and of course you have to restart Baldurs Gate 2.
