Yes, I do have the game registered. I uninstalled it (with the disk), and then reinstalled it. So now it's working, but I would still like to know where I can re-download Sins if something happens to the disk.

 I am not sure whats goin on, i purchased Sins original from the store, dont know if i ever did register this copy. I purchased the trinity pack and had it on my pc at one time, since i have sold my old machine i used my discs to reinstall Sins, but i cannot for the life of me figure out how to get trinity back on my machine, it was an electronic purchase of the trinity pack. I have tried redownloading it from the website but i get lost in a lot of updates to gamestop/stardock sites. i could really use some tips, i really love sins but since i got trinity its just not the same without it! please help
