Group problem/Buddy Icon Error

OK, I am trying to reorganize my buddy list, putting people into new groups and such forth. After I put them into the groups and go back to my buddy list, an Error Message pops up and say something along the lilnes of “You buddy icon is not showing, but had not been lost. Please try again later” Then all the new groups go back to the way they were originaly. I’ve tryed exiting AIM and starting again, restarting my comp,nothing is working, same result. Any idea?????
