Hmm, I don't understand why you didn't download the newer ones (12-10-2008).
0911 isn't the latest client, that's the problem.
I heard the patch FTP password had changed and so you must get the sakray.exe of 1210's in order to complete the patching process (it's about 3mb, worth a try before you get the whole 1gb new client).
I think I uploaded them for someone before, they are here:
http://hosted.filefront.com/ratemyserver/2368168So if you want to try, first you must rename or move the current sakray.exe and ragnarok.exe outside of the RO folder so to have a backup. Then put the new downloaded exes into the RO directory and try patching rag and sak.
Use at your own risk, these are exes ... at least do a virus scan on them if you can.
