Cant intsall

Hello I purchased Gal Civ2 shortly after it was released.I purchased it via download. I installed it on 3 of my computers without any issues. I have performed updates no problems. Yesturday i saw patch 1.11 was out so I uppdated through Stardock Central no issues on my computer in my wifes store. I got home last night and tried to update the home computer and it wouldnt download through SD Central. I got and error of invalid authorization. Tried it 3 times, same issue. So i downloaded it by using the stand alone download on this site.

Now today I decide I want to put it on my laptop, so i download SD Central and install it, I go to Games and it flags Gal Civ2 as a purchased Game and available for download. I start the download and get the same error, invald authorization and wont download. I have retired numerous times with and without reinstalling SD Central. I am getting somewhat irritated.

Any Ideas?

thanks
