I'm in the same boat. Emails weren't sent out until somewhere in Mid December, so us returnee's had NO idea about the server opening until then. Then like any sane person, I played as f2p/preferred while leveling up new characters on SV because why would I pay to play free content that I've already played several times in the past (legendary status).
Then when I decided I wanted to sub, my account had payment issues due to being an "old and inactive account" and needed to go through support after the holiday period to get it sorted out. So even with the update, I am still not eligible for free transfers, and I will not be paying for transfers as a Founder with hundreds of $ through subscription alone. Especially since they seem intent on killing the server for whatever reason. Even if they backpedal all the way now and just have "be a subscriber for free transfers" as the only restriction, or give preferred a couple free transfers, too much damage has been done at this point.
