Thanks, HW3: I bought SH3 in March 06 and was surprised it needed a DVD player to download onto the computer. A few days ago I finally got a new computer and installed SH3 and was confused when I entered the 6 letter code and was told it was wrong. I went to the Ubisoft site and tried to register so I could contact technical help - only to be told I had entered my name incorrectly. Ubisoft's site isn't very client friendly and I was all set to return the sim and get a refund. Thanks to your posting, the sim is up and running.
