There is an error which is not in english so i cannot understand it what is it about.
I've unistall and reinstall Tanki Client but still no use.
Here is the error..
I also got this problem once. I rebooted my modem and reopened the client then it was working just fine for me. If doing so didn't help you I would suggest running the game on Google Chrome or on Standalone Flash Player
Which operating system are you using?
Windows 7 classic theme
