I've purchased Linden dollars a couple of times last week and weeks prior, now I can't purchase any Lindens dollars at all. So I tried to update Payment info and now the system will not accept the same card I have been using. I have plenty of cash on my card. I called my card company, they told me they are not blocking anything. I called LL they didn't have any answers except to keep trying. Any ideas why this might be happening?
