Can't download from gamecopyworld - http server error 500

Since Friday 11/13/2017, everytime i try to download from gamecopyworld.com by clicking the disk icon next to a (ANY) file, only a frame with a blank page opens, nothing more. Inspecting the source of the webpage reveals a redirect on click to http://dl.gamecopyworld.EU/, which in turn gives a http 500 internal server error on direct opening.

Search on GCW (the custom google one) also doesn't work (error 500), because it links results to gamecopyworld.eu. When changed in adressbar to .com, the results appear; this however doesn't work with downloads.

I have no adblocker/script disabler installed; even tried to turn AV off temporary, to no avail.

Fix this please.
