I have been using SL for a few years now, but hadn't logged in for at least a year until about two weeks ago. Since logging in again I have had many problems; 1) I am unable to teleport and do not receive teleport requests from my friends 2) I am unable to change clothes 3) I have purchased new clothes since trying SL again, but the clothes do not appear in my inventory Can anyone help? What is the possible cause of these issues? Thanks!
