I had to reinstall completely my WHS server with WHS 2011, due to a disk failure.
I had the capacity to recover all files that I put on another drive. I have tested directly sample files (flac mostly). They are all working.
I tried to import the files in brand new J RIVER installation based on the latest release (178).
None of my files was import.
Here is the log.
Thanks for your support
