I'm trying to run the updater but it keeps crashing on the first file.
It says "Patch has started Elf..ukx" and the blue bar gets almost to the end, but then it freezes and encounters an error, causing the updater to close.
Hum, it might be a good idea for you to download the PTS to Live convertor file. All the conventer file does is replace the L2 launcher .exe, so it may fix your problem, and you'll be connected to the correct update server (ie. not PTS, but Live).
I had both clients on my PC, and I just copied all the PTS files into the Live folder.
I've just deleted the "animations" folder where the problem file was, and it seems to have done the trick.. although animations take long to download >.>
