Unfortunately I'm not sure why these problems occur for some people and with some accounts.
Things you can try:
a) Just wait WITHOUT being logged in Close CS2D Wait 15 minutes Start CS2D again When logged in try again
b) Change password Remove password in CS2D Change password on the website Enter new password in CS2D When logged in try again
c) Reset connection Close CS2D Reset your internet connect (reconnect via router / modem interface or disconnect from power for half a minute) When connection is back restart CS2D When logged in try again
