After Fitz and I troubleshooted this problem this morning and came up with the above solution, then I found another one. If you'd like to do it easier follow this...
1) Get in game
2) Open Tablet (Shift+M)
3) Click Issued Citations
4) At the bottom, click "Player IDs"
5) In the Player Name column, locate your steam name. This name may be different than your current steam profile name. It was the name of your profile at the time you got whitelisted.
6) After locating your name, look in the first column and copy the NUMBERS ONLY and it should begin with "110..."
7) Paste this number in the steamAPI field in your identifier window in CAD.
