There are alot of my contacts from my contact list who have dissapeared. I mean that I don't have them in my contact list anymore. This happened to persons from one group. The account is yahoo.

The thing is that I was using yahoo messenger for mac and (previously I was using adium) I have decided to switch back to adium. At first I didn't realize, but only one day when I sent a message to a person and this person suddently dissapeared from my contact list afterwards.
I added her again and she told me that she didn't do nothing. Today I took a look at my contact list and more than 30 contacts are missing.

I need help. Please tell me, if u know something about this error or I should roll back to that beta messeger.

First thing first: the easiest way i can think of to add your friends again would be to look at your chat logs.

Now, what version are you using? And are the contacts lost in the official client as well?
