Yesterday i.e. 22-04-2011 when there was some problem with Nimbuzz in which we faced login problem and No contacts in list problem. Later Nimbuzz was fixed but still i was unable to see my contacts, later my friend suggested me a method following which i got my contacts back.
If you are facing the same problem follow the steps
- Log off your id which got the error
- Login to Nimbuzz using some other id and sign out again
- Now Login using your old id again. You are done :p
