So I installed Windows 7, but before I wiped my hdd i made a back up copy of the whole playonline folder. Thinking I wouldn't have to update.

So I used the 2008 collection dvd to install POL + FFXI and all expansions, just so it puts the registry entries in. Now I take my fully updated Playonline folder and delete the old one and copy the new one. However now FFXI won't work when I try to start it asks for the Final Fantasy XI CDs. And this installer thing pops up.

Did I do something wrong? Or is there no way to copy over a updated Playonline folder and I just have to reinstall and get the updates off their slow update server?
