Login-Issues & Bug reports
Hi all,
we are totally aware that many players are not able to login because the server is often totally crowded. We try to give the test environment more resources next week, but for the moment we only can beg for your patience.
Please use only the forums here on the test server for questions and bug reports as the support of your country will not be able to help you in any way. You will get help only HERE on the international test instance.
Please accept our apology's and have patience till next week.
Thank you!

Unfortunately there is no support for the Test Server,but all questions relating to it,should be directed to the Test Server Forum Test Server Forum Link
If you can't register and unable to write test server forum, try search test forum to answer.
