I think i know what causes the "Cant connect to server error"
I noticed i couldnt connect for the past few days when i actually never had any problems connecting.
Now here is comes
I noticed the "Checking HDD", but i clicked the screen when it was checking for HDD stuff.
And yes i couldnt connect again...
so i restarted hoping it would work, i didnt click the screen en noticed the Checking HDD changed into connected to server or something like that, and yes i pressed play and instant connected.
So here's a long story short.
Try not clicking the screen when its checking for HDD, watch the message change, saying its connected (same popup)
Wait a couple of seconds like 10 and press play, hopefully it works for you.
Give me some feedback if this worked for you.
I tried it 3 times in a row and i instanted connect all three times.
Hope this helps u guys out
