Micro Converter SDI to HDMI 3G not working after Update

After an Update (9.0.1) of my 3 Micro Converter SDI to HDMI 3G they are no more working!
The Update (9.0.1) on Micro Converter HDMI to SDI (i own 2 Pieces) are fine.
The Update (9.0.1) on Micro Converter Bidirectional (i own 1 Piece) are fine.
So my 3 Micro Converter SDI to HDMI 3G are BRICKED !!!!
Why is no downgrade on The Converters Setup Software?
Blackmagic, please help !!
