Since yesterday night the downloads for the client patch 1.5 are open - size is 3,075.1 MB. Should you use the official launcher to patch, you'll only download the patch in parts and the launcher tells you some mumbojambo about the patch being applied after 31.08. or something. IMO the best way to download the patch or the alternative methods as follows:
Fileplanet (you don't need to be a paying subscriber)
Apparently there is a glitch in the 1.5 client that lets your OK button appear above the password field, others have that as well. No need to panic. ;)
Update: Just to let you know, i downloaded the patch via FP and after the install the NCsoft launcher gave me some error. I just closed the launcher and started the game (think you can also restart launcher and check for updates), which then gave me the info in the launcher i pre-downloaded the patch which would be applied on 31.08.09 - so thats normal.
