DM7000 : Enigma1(I imagine !) : Firmware 1.08

I've had my DM7000 a couple of years now but with a lengthy lay off of use. My recently renewed activity has reminded me how frequently the box locks up requiring a reboot when doing ostensibly simple things with the remote control ! I had expected to find a more modern version of the firmware by now, hoping this would fix the issue. Any suggestions why this happens and what the solution might be ?

Thanks

Dave
