[Having problems with profiles on V2]

I am having a problem also, but it is viewing a person's profile.  Many people are good
and the profile shows without a problem, but then on some others I get just this
"This name is unavailable." and nothing else.  Now  someone the other day
fixed theirs and with some checking with others using Phoenix viewer they
are not seeing a problem.  I am running the latest SL viewer 2.5.1, dated March 1st, 2011

Any ideas on how to fix this or what the problems is?
