Orion stops working!!

[Sunbay]

Hi guys, i hope i can get some help..

Orion just stops working after a few seconds! In playlist, it sudden stops. I can still click on the vst's and everything and open them, but nothing plays. Even if i'm just freely playing on my midi keyboard, the sound just stops!

I've tried uninstall it, re-install it, downgraded it to version 8.5 (i was on 8.6 and always worked good).

Don't know what else to do!!!
