So Both MIR and Kontakt had an update, however the problem still persists. Here is an interesting thing I just found though.
I have been always using Herbs preset or picking a starting point in MIR. This time I decided to just load a venue with no instruments and it worked fine (Kontakt and MIR could stay running). I then added some instruments (SE Presets of Orchestral strings) as well as full Appassionata presets. Everything worked perfect!
I then added one instance of Vienna Imperial and boom, Kontakt stopped working. So I closed Kontakt, closed MIR and relaunched them both. Loaded the Teldex venue in MIR and everything was good so far. I could play Kontakt fine. I then loaded Vienna Imperial and again it died. I then loaded the starting point, Vienna Imperial Solo and it died again. If I even think to use Vienna Imperial in MIR I can get this result 100% of the time.
So back to try a few more combinations but it seems some of the Vienna Insturments work while Vienna Imperial doesn't (which makes sense to why my projects aren't working, I ALWAYS put a piano track of Vienna Imperial in my mixes, even if only for myself asI play the parts in live). Also, NONE of the starting points or presets from Herb will work. I have to start with blank MIR Venues to make it work with Kontakt 4 at the moment.
