I'm trying to use the Switch Device Wizard to go from my 8310 to my new 9000. Everything works with the 8310 and then when it goes to the 9000 to load the settings it says:

"Invalid Configuration - The application "Download Manager" cannot be loaded because some required files are not available."

I'm using DM 4.7 and OS 4.6.0.167. I've wiped with JLCmdr and have reloaded the OS. Still not working...Anyone ever seen this???

I would try DM 4.6 next (nothing to lose), have heard stories about 4.7. Perhaps someone else can confirm.
