I'm starting to believe the patcher is having issues with the new patch type.
Repeatedly closing and opening the patcher will eventually work. It seems to hang after it finishes downloading, and restarting it starts it on the next patch.
However, it seems it will eventually get all the patches downloaded and working. There were quite a few.
Sorry for the inconvenience.
Alternatively, you can download the
abdatagrf.zip here . It comes with our all-in-one (kro/renewal/aro) patcher, which can handle the new patch file type.
I don't think we did a proper launch for it, but I plan on packing it with the abdatas from here on (as long as I remember).
Also, the new client will launch with this patcher.
