Jimmy,
After working with Phillip, I found a problem that may be what you are having. Phillip had downloaded and deleted a series of audible book files using the program called Audio Manager. We do not produce Audio Manager so I can't say why it does not fully delete these files, but after some testing we found that references to these files still remained in his memory after file deletions. This caused MJ's Plug-in to crash. I posted a new Plug-in yesterday that hopefully works around the inability for other programs to remove these files fully. Please get the latest version of the v8 Plug-in (v 3.0.
and see if your problem goes away. Try reformatting your card (right-click on Rio-800 after initializing the player) and see if that helps.
If you are still having problems, search on your PC for the following files,Rio8drv.sys and Rio8drv.inf and let me know the dates on these files.
Thanks.
