Well, you certainly can but I don't see where that gets you, unless you want to start all over again.
If you're not sure how to do it (though I'm convinced you are):
Go into the game with the character you want. Go to their record form in the game, and you'll see the export button down on the right hand side. Press that, and save the character with a memorable name (you'll see where to write it) something like "I'll finish this even if it finishes me".:joke:
Exit that game once the character's exported, start a new game and go through the character creation process, but hit the import button where the export used to be. Call up the character you've saved and there you are.
However, this will only export the character and not their items or where they've been, so you really will be starting again, but with an experienced character from the get go. (Edit them back in)
Make sure that the game is installed properly, and that you've patched it accordingly. Also, sound cards are one of
the biggest problems when it comes to playing games. The computer tries to play .WAV files for the game, but your computer can't actually do it so it crashes. A lot.
