I have the problem which is that when using Chrome nothing happens when i try to download a game. it doesnt even prompt the use og the Downloader. I tried with IE 8 and nothings wrong there also tried with Firefox nothings wrong there either.
Ive tried all the Registereing steps i could find on the forums, ive tried Regediting it, uninstalling and reinstalling it to no effect at all.
and the odd thing is that it worked perfectly just a few weeks ago.
I'm having the same issue but thought I would provide some detail in case it is any help.
-It worked just fine for first two downloads via Chrome
-Has since stopped working, no error message just never launches downloader
-I used the reg edit suggested fix and when i went into the local settings for Chrome and was supposed to set gogdownloader to false gogdownloader wasnt even listed in the file i opened in notepad
-i uninstalled both chrome and gogDL, and went into directory and deleted all files, reinstalled chrome then gogDL but no change
Not sure why it worked the first couple of times but not after.
Anyway hope this helps. Hope its fixed soon. Everytime I open IE i die a little inside.
