... use Internet Explorer.

Not sure about other browsers, but for me IE is the only one that works at the moment.

Control and F5 has got me out of the black hole,but for how long who knows.

changing the url to "https://" worked for me in opera.

Using Opera also.

Relogged on Cyberfox 38.0.6 and everything works fine now.

Seems to be fixed for the moment.

I wouldn't use internet explorer even if it was the last working browser available. ;)

I've just waited some minutes, without doing any logoff\login (just a refresh), and all went back to normal.
Anyway, GOG should get the good habit to inform their users about site updates and temporary issues..

hahahaha,I like your sense of humor:-)

I have only just regained the ability to post.

I tried many browsers including Arora and Konquerer. I even tried posting from virtual machines, and it didn't work.

Seems back to normal for me on all browsers now.

I use IE and can post fine (BUT cant access the Sale page. I have to use FF for that).

+1 > me too ;))

I can't use Internet Explorer on my compuer at all because I don't use Windows.
