So, in the specific, what kind of problem do you experience exactly today when you try to connect?
The game's freezing as soon as it loads the main menu:
- the freeze in action.
The quality is a bit crap, but you can easily see how the cursor stops moving the moment the game freezes and even the windows pointer only shows up when I move the mouse away from the page.
It's been like that for me since the 18th. As I mentioned before, the challenge only worked twice - once on the 18th at at 11:09 and the second time on the 19th around 22:18-22:27 where it allowed me to play several times before starting to freeze again.
If I use Firefox I can wait 5 minutes after which the page unfreezes, but clicking the "Challenge" button only results in the "Giveaway locked due to suspicious activity" message. It doesn't seem to unfreeze like that in Chrome.
I tried 4 different computers and that bug is present on all of them.
