How can I activate BBM on my Bold again ?

Hello Guys,

i wanna switch from my BB10 device to my Bold.
But how can i activate BBM on my bold ?
It ask me about my BB ID and thats it. But i can not receive or send messages via BBM.

Is there no way back from a BB10 device or what can i do ?

I can not send invitations or add some other PIN. My Android BBM (another ID) scans the Bold BBM Barcode but nothing happens.

Is this service shutdown ?

THX :)
