Behringer RD-8 firmware update Version 2.0.6 problem ! does not let me update, it is blocked !

New

Hello, i use Mac Osx High Sierra with SYNTHTRIBE V 2.4.3.....i had already updated my RD-8 months ago to 2.0.2 without problems! Today I tried to update to 2.0.6 and it doesn't let me do it .... after about 5/6% it stops and doesn't update, an error message appears! The tragedy is that now my RD-8 when I turn it on DOES NOT WORK, the 16 STEP lights remain on but everything else is stopped, it seems blocked! HELP!
