Hmmm ok,
i never tried that Link before cause im only used WART or Miranda for registering the two Landlines over one Year before.
The Mobilnumber i registered over 2 Years before on an official Client but didnt used that official Client for all the Time.
Maybe for 2 Months and then i deinstalled WA on Mobilephone and reregistered that Mobile Number on Miranda and used it until now.
It seems that ur Main-Account is realy blocked cause its unpaid
Maybe it resets after a Time of "Sleeping" but dont know.
As i said before maybe others here on Forum can post theire Experiences with that.
But anyway u can registering just another Number and make an Account for use in Miranda.
U only have to tell ur Contacts about it ;-)
