I'm trying to load the Risia client on my system, which already has the regular client installed and functioning. The standard client was re-installed after the downloadable was modified to include Hi-Res drivers and the new "TurbineInvoker" launcher, and has been, other than getting occasional "DDO client has stopped working" messages when trying to start up, working fine.

The Risia client seems to still be configured to launch using "dndlauncher" for one thing, and after installing, updating and restarting the client, at the "updating the game data" stage, about halfway through the 9802 or so files I get an error that says "cannot save data files", crashes the upload, and tries again after 60 seconds, to no avail. The file it's crashing on is "client_sound.dat-12111" or something very similar (It's off the screen so fast I cannot be sure of the numeric portion).

I have turned UAC off and I ran the installer as Administrator (started by right click, etc.)

The regular game client did not give me any problems when I re-installed. Has the Risia client been updated yet? There are going to be a lot of players wanting to get a preview of mod 7, and without a working installer/updater there may be an uproar.
