Deleted my acc, got whatsapp-code sms without problems in Mitakuuluu but still not able to register - the circle is spinning endless!?

Edit:

Ok I was able to register with Mitakuuluu now. I don't know what caused this problem... I changed from Wifi to 3G, deleted my .whatsapp folder and tryed it with voice call - I didn't receive any call but it registered automatically (I also had to repeat this procedure after copying my old .whatsapp folder back).
