can't re-download

I bought space rangers 2 rise of the dominators with SDC and have had to completly wipe my computer bacause of a virus.  I've just got the urge to play it again and have found that SDC was replaced with Impulse.  I downloaded and installed Impulse then logged in with my old log in info but none of the games I bought and registered showed up.  Is there any way for this info to be migrated?
