The Flyers theme was dl as a MyColors.exe and I used Winrar to extract it to a folder and then from there I installed everything.
The way it works now is you get the DL link then fire up MyColors and hit Add in the bottom right hand corner. After dropping in the serial number MyColors goes through the DL motions and you are all set.
Not for me I put in my email and S/N and it said "There was an error validating your Registration Information please try again." It did the same thing with the Flyers theme. That's why I extracted it into a folder.
I'm just trying to find out if I'm doing anything stupid before I contact Stardock.
