Oh, my onPC System startet even on an totally uncompatible AMD Processor. So it might not be the system...
Did you try a clean start as well?
It sounds a little bit crazy to start a software in Win8 mode which recommends Win10 for proper use... ?
Yep, tried clean start as well. De- and reinstalled several times with cleaning all Program Data. Redownloaded installation.exe. Havend had any issues with my 'uncompatible system' since MA3 came out. Yep, sounds wrong to run a native win10 program in win8 compatibility mode, but as long as it works for me... All works fine, i can output artnet, go in session with other onPCs and export show and use it on another system. So im fine with it for now for programming. Wouldnt run a show with it, but that was never the plan anyways.
