Sorry for my Englisch I speak not so good.

Sunday I wil make a online flight by IVAO.
I install IVAP with TeamSpeak2
By IVAO I was online but I can not speak with the ATC with Teamspeak2 because I recieve the message: Bad Login (name and/ or password wrong.)
I can login by Teamspeak with my username en password.
I try it with my username and password from IVAO but also I recieve this message.
And in The Eye from IVAO I was Online and I wil use Teamspeak and also there this message.
What do I wrong? Can someone help me please?
