Does anybody has update 1.3.3 or lower because I wanna reinstall software, something strange is happaning to O and I'm not sure what that is.
When I'm in Combi mode it returns or forwards combi for 2 numbers (up or down, or goes in program mode ?!?! Display at some point doesn't react, so I catch that I need to swipe with finger from left toright on lower part of the display and then it works, but thatn after few moments it does it all over again.
Also in disk mode when playing wav file it stops it after while!
Could that be hdd problem or motherboard??
Maybe I could try to see what happens when I instal older software..
That behavour became like a 3 month ago, maybe I need new RAM memory, I can't figure it out
