Major problems happened after updating MyBookLiveDuo

Hey guys

after updating my Hard Drive to (02.31.08-067 : Core F/W)  , my SONY BLU-RAY HOME THEATER SYSTEM  is no longer reading any kind of video files using DLNA like (.mkv, .avi, mp4) and many others, Which was perfectly working before this update.

P.S. Ive tried to format the hard drive and rebuild the dlna but non of these made any improvments 

According to the release notes several issues with DLNA were fixed, in your case seems to be the opposite.  You can try resetting the MBLD by holding its reset button for 4 seconds.  

I appreciate your help, I’ve tried to make a hard rest several times but it didn’t solve the problem
