After dealing with GamersGate Download service for the last 40 minutes, I can say I'm displeased and requirem-less
"Check your firewall and download *naughty*"
I disabled my firewall mate and got no anti-virus turned on.  The *naughty* does it want me to do now, install viruses so it knows I have no firewall?
10:45   Still no luck.  I checked their forums and they're filled with similar complaints for varying games; I will try their alternate downloaded once I find out 
 How To *naughty*
 Uninstall Their Program
http://www.gamersgate.com/downloader/Downloader.msi
10:52    Is the program still a beta?  Jesus christ, it has no offline help.  It's "help" tab only tells you the version and name of the program (gamers gate that is)
Continuing search of a *naughty* uninstall.
10:57 Found an uninstall; in the link I gave above.  The main download offers zero .exe for uninstallation.  At all.  No start-menu uninstallation, no in program uninstaller.   Nothing.
Every single commercial penumbra release has been plagued by problems.  Jesus Christ when will it end.
11:01 A *naughty* surprise in this *naughty* orgasm(naughty?) of GamersGate.   It still doesn't work, surprise surprise.
GamersGate passed the point long ago in being effectuate or time-saving.  Torrents (even with their slow download speed) would be more effective and time saving if it downloaded the game at 20kbs.  
I've purchased the game legally at gamers gate, I should be able to download the game legally.  
What it feels like right now is they're trying to screw me out of money that I worked for; no download program (steam, impulse, stardock central) has ever given me a bit of trouble in the slightest doubt.  Their staff seems to do nothing despite the large amount of complaints.
11:57 After several uninstalls of gamersgate (with registry removels checkin afterwards) and trying both of the installers, I have yet to download the game.
Great program GamersGate; shows potential but horrid customer support.
