Hello..the past few days I've tried to buy Lindens inworld by pressing Buy L$ as I usually do and getting lindens that way, now when I press Buy L$, I get this message on my Firestorm Viewer: Unable to Buy You do not have a payment method set up for buying currency in the viewer. Visit https://secondlife.com/mylindex/buy php?associate_for_viewer=1&lang=eng-US to set one up. I've been in SL for over 15 years, and I had my account set up with a credit card. What happened? Thanks, Woulfcat Singer
