Carbonite is back!!
Carbonite has posted a beta on their web site and I installed it and it seems to work --- mostly -- warehouse didn't work but I probably need to take each character to the bank again before it will work.
It says to delete the previous carbonite folders from the Interface folder before installing. I copied them to a directory called Old Carbonite just in case I wanted them back ... but it looks like everything is probably ok.
It isn't on Curse yet you have to download and unzip and drag to the Interface folder yourself. No big deal.
