Starting on 6/28/2013, every time I try to log in, all I get is this error message and I can't log in : " Login failed. Updating friends list. " I have uninstalled all but the one viewer I use, which is Singularity and I have done a clean install of the latest version too. Any idea or help greatly appreciated. Thank you. 6-30-2013 UPDATE - after some research I found the answer and it was really easy - all I had to do was download the latest Linden Labs SL Viewer and log in with it and that solves this problem ! Now my Singularity Viewer works perfectly fine as it did before ! Thanks to those who posted replies here - I had found this solution while researching in the middle of the night after I had first seen this problem and before I saw any replies here to my post - but thank you for posting your replies and answers and thank you most of all for the time and concern shown for this problem I posted !!! Thank You !
