Like it says above. I picked up AD2 shortly after I got X3 so now I just want my goodies! :-)
 

Did you get s/n and/or reg codes for the packs? I'm guessing you would just apply them to your XLN account and then go shopping.

1. Run the XLN online installer
2. Got to the Register Product Key page
3. Enter the key from the Control Center
4. See the available deals
5. Make your choice
6. Install!

"Product Key does not exist"
I'm copying the serial from the AD2 in the Command Center, which I didn't install because I already have AD2 installed. Is that wrong?
 

Belay that, XLN installer is caps-sensitive. Time to shop!!
 
 

I always manually type stuff like that because occasionally there will be anti-pirate/spam/phishing/whatevs things that screw up various computer registration dealies. Also sometimes certain characters you see may be generated in some wierd non text/alt text format that can screw things up. Copy/Paste usually works for most things but after getting turned around and discomboobulated by such things enough times I just take the time to type out whatever I'm entering. I get unnecessarily enraged by programs and websites implying I'm full of shiz and fail.

I had the same thing happen.  After typing the number in several times, it finally worked.  Not sure if I had typos or the site was acting up, but a little perseverance will go a long way.
