Just an FYI for anyone else who needs to do this without Steam...
Your characters follow your Warband Serial key, so just install Warband on whatever PC or Laptop you plan to play on, install cRPG, and 'create' a character with the same exact name as the one(s) you play on your other PC. You don't have to worry about fixing the face or anything since that's already saved on c-rpg.net.
Next, log into c-rpg.net, then in the cRPG mod log into your new (same) character that you played on your other PC and everything should be there soon as you enter your 1st battle.
I had to do this with a PC / Laptop combination so I know it works.
