User-mode Driver Framework Host Process has encountered a problem and needs to close

I have a e280 and have been using it with Napster to Go for a couple years. Computer runs XP. Suddenly, we get this message when we plug in the Sansa in MTP mode:

Windows Driver Foundation - User-mode Driver Framework Host Process has encountered a problem and needs to close.  We are sorry for the inconvenience.**  **

error signature:

szAppName : WudfHost.exe     szAppVer : 6.0.5716.32     szModName : WudfHost.exeszModVer : 6.0.5716.32     offset : 000130f5    

technical info about the error report:

C:\DOCUME~1\EARLDA~1\LOCALS~1\Temp\WERb6aa.dir00\WudfHost.exe.mdmp

C:\DOCUME~1\EARLDA~1\LOCALS~1\Temp\WERb6aa.dir00\appcompat.txt

Sansa works fine in MSC mode, but then I cannot sync with Napster. WMP 11 has the latest updates. I tried many Device Manager tips that have been mentioned, but it will not successfully install.

Any thoughts?

Thank you!

You can try rolling back to WMP 10, removing the user-mode driver framework (from control panel -> add/remove programs), and then update back to WMP 11.  It might even work with WMP 10, so try before updating back to WMP 11.
