wow!! i will be reading faq very closely right now
mm, on a closer look, the problem is not quite solved.. i mean, the exp and lvl where right all the time, the problem was the HP, that lowered a lot from game to game :s
This is what i did:
I changed char1 name for another (Matias.char i think). THen i copied to characters folder in bg2 the file, and then imnported the caracther in a new game. After that, i started, and had the HP lowered :s
EDIT: i have just tried exactly what you mentioned in the FAQ Galuf, but all i got was a TXT file saved in bg2 char folder !!! and, as i figured, couldn't import it from there when i started a new bg2 game :s
This is really getting on my nerves....
