Log in using your Tanki Online account, just make sure your rank is equal to or higher than Gefreiter.It is just the problem with the CAPTCHA which has been updated so there
might be some problem with the new pictures which are not completely
well developed yet. Just keep trying.Or you can try to log in with different browsers like IE, Chrome, firefox, or Safari.
