I launched Ryzom with this last night, played for a few hours and managed to quit without a crash... I just tried to do it again and wound up starting the process of getting a 183.4MB patch. Upon being told there was no new patch today I exited, restarted with my old-fashioned ryzom.exe, and wound up needing just an 11MB patch - probably to fix whatever I'd just been allowing to happen.
Not sure if the issue was caused by Rystore or my fruitcake of a computer, but I figured it was worth a mention.
Edit: Tried launching with Rystore again the following day and it worked just fine, so I think I'll blame the Ryzom background downloader.
