Maybe someone just forgot to renew the certificate...

Bought Painkiller before this problem appeared, only now getting around to the download and the gog downloader gave me a whole load of messages about invalid security cert

Same thing here. Just saw it when I clicked on My Account.

Same here. I wish some of the GoG guys would come along and answer or solve this problem soon. I wanted to buy something.

just popped in to say ive got the same.
it appeared when i went to try and buy under a killing moon.
was going to add it to exceptions, but thought better of it at the last second.

Same thing on my end, can't access my account. Hopefully GOG fixes this soon.

I've just contacted GOG via support, so hopefully we'll have some info soon.

Same here...

And I see it too.
[EDIT] If this is a developer error, I hope GOG will post pictures of his public spanking in the corporate parking lot :-D
(I'm a developer myself, so I know these things can happen. Hell, I've probably made worse mistakes myself.)

i was going to do the same but then thought if this place has been hacked (probably unlikely) then they would get my details that way or at least my email address.

Hopefully someone is in the office today, from what i have read GOG staffer are not available on the weekends.

Many of them are known to browse the forum in their spare time, however. Hopefully one of them will see this thread, if the support mails aren't read until monday. Having all their customers essentially locked out of their accounts for an entire weekend is not a good thing. Especially when there's a promo on.

Yeah same here..I added an exception and it works fine..though since reading this I have removed it.

Same here. I was about to purchase. Come on GOG, you're loosing money! :-)

On the sidenote, whats a security certificate do? I'm doing a website for my parents and when trying to login to the admin section on the webhost's site, it gives me the same invalid security cert error. I'm kinda worried about it
