I just purchased the entire collection of Baldur's Gate 1, 2, Thrown of Bahl, Icewind Dale 1, Heart of winter, and 2. I can play the games but it will not let me load a saved game on any of these. If I start a new game then it loads characters I made from a previous game. What do I need to do to fix this? They were my favorite games back in the day and I spent good money to get unopened copies of them.

Atari owns those games known, you'll be able to get support from them.
