Does not work WD MyBookLive 2T and Pioneer BluRay BDP LX55 (in streaming mode)

 “PLB MSG DMS BROWSE FAIL!” on Pioneer BDP LX55 & WD My Book Live 2TB 

I have problem with error (shown above) when BDP works as streaming receiver via LAN(when I look for pictures or music written on WD).
It appears when I drill down/up catalogs. When this error appears is enough reset BDP and start whole process once again. I updated firmware on both to newest version but it did not help.

Any idea how to solve it?

Thanks in advance.
