I was playing the barbarian in Diablo 2 on Nightmare Mode and had him at Level 43. I installed the expansion pack, picked a new character and played her for a bit. Now I want to play my old character but he doesn't show up as one of the characters I can select. Only the new person I created is there. I went to the Diablo II folder and the Save folder and the files are there for both characters so why can't I use my old character?! HELP!!
