I purchased the 3-pak of Descent 1,2,and 3 from GOG.com and then installed the downloader GOG Galaxy 1.2.32. I had no problem downloading Descent 1 and 3. But when it came to the final download of Descent 2 I clicked on INSTALL from the drop down menu under the game, and a greyed out window appears with CANCEL and CONTINUE buttons at the bottom, and a rotating circle leading me to foolishly believe it's about to do something. I've tried several times now with the same results each time. I even pinged the site to make certain it wasn't a networking issue. Any suggestions?

i know this is really old, but its doing the same thing for me. did you ever figure it out?

I always have to start the downloads and leave them running, then quit & close Galaxy also making sure to kill any left over Galaxy processes in task manager, then start Galaxy again for the downloads to finally start.
