Can't Find File Error Code (C00D1197)

I’m using WMP version 11.0.6002.1811 on a Vista Home Premium with Service
Pack 2 operating system.

I have successfully burned many CDs from my library. However, I’m now
encountering an error message that indicates the burn can’t take place
because the file can’t be found (error code C00D1197).

This error makes no sense to me. The files are in my library and WMP can
find the files to play them – so why can’t it find the files to burn them?

Any suggestions?

Thanks for your help and time!
