It didn't work via paypal (error message) and when i clicked the "back" button it just transferred money to gog. Game doesn't show up

Contact support (remember that the form is broken and doesn't give you a "message sent", but it will still be sent) they are usually fast with this. You'll probably have the game (or refund) by tomorrow noon.

Use the support form, send your complaint, do not worry about it sending you back to the "Choose your error" form without reporting success, or wait for a blue post to tell you they are aware of the problem and working on it.
Shouldn't take more than a day to fix it, and it will probably take less.

Edit: Damn ninjas, ninjaing the ninja....

I sent a multiplayer key request yesterday and did get a message sent confirmation (took me back to the starting page, but I had a green box on it saying that the message was sent). Not sure if this means that confirmation messages are fixed now or not.

Still no response

Hey yo, GOG. This issue is now your top priority. By not fixing this you are actively depriving somebody of The Guild. This is unacceptable. All Gogers must own a copy of The Guild have put over 24 hours of play in it within the first week of buying.

We could start posting porn vids in this thread, that should get their attention....

Anyway, the OP might consider to PM one of the blue guys. A payment issue shouldn't be in limbo for a whole day.

Edit: Ah, for the hell of hit: Raunchy Porn incoming

I heard they were out of stock.

Oh...my. And it's in HD as well *_*.
Here's my favorite amateur scene - really tender stuff...

And that was even part of my birthday money.

thx

Be honest, it was the porn ;-P

You're gonna have to add the game to everybody else's account, too. It's vital that everyone experiences The Guild.
