Try adding your account to gmt2 before it is created, then create the account using the embed browser. Your account will automatically login once your account is created. This isn't possible I am afraid. There was an issue with some thrid-party library not working properly on windows server os. Should all be fixed with the latest version 0.6.13. If you reinstall, you will be asked if you want to restore your previous save, so all your settings/accounts will still be there.
