Like the title says I'm having issues with downloading any of the goodies from the two Stalker games. If I try to download them using GoG web site I just end up with a ''403 forbidden'' error. I've also tried downloading them using the client but then I get a ''server error''. I can download both of the games fine.

You could try the account refresh thing which might help https://www.gog.com/user/refresh , then try to download them again.

Though it might be something you need to contact support to solve.

Thanks for trying to help. I've already contacted GoG support they told my to try downloading via GoG client or changing the url to the download (remove the ''s'' from https), unfortunately neither worked. I've also tried your solution but no success.
