This has happened with every single downloader I've tried to use. I've always had to download the demo and then activate it, which is all good except... today when ep3 is released to the season buyers first :(
It's mentioned elsewhere in a thread here that it's a firewall issue.
Is there any way Telltale could be persuaded into providing an actual real downloadable version of games when they come out (accessible as an alternative link or something on the 'Past Purchases' page?), instead of the current setup?
It seems that every person who has a secure computer system would be unable to use this program.
