You're telling it you're from Canada. I'll add an option to BNetLogin to specify other countries for beta42.
EDIT -
Nevermind, iago already had this one taken care of.
In your home directory, go into .javaop2 (folder) and open [BotName].jbb, where [BotName] is the bot you're using. Find "[battle.net login plugin]", and where it says country=canada, replace that with country=duestchland (spelling?) and where you see countrycode=CAN, replace that with countrycode=DEU. I'm not sure if those values are correct (let me know if they're not), but I believe they are.
