Topic: fireface 400 Crashes win10 randomly but regularly

I am ANGRY ....after complaining about crashes, you told me, i should buy a TI firewire Card (30euros)...that did not change anything    ...
I just changed the Encoder on my FF400  and had 3 Days without crashing, because i was using Bluetooth Sound ....
Just solderd the new encoder (14euro delivery via NL post 12 Euro   wtf )   
Pc instantly starts crashing again

so do i have to buy a new Interface ? or will you fix that error ?

newest firmware   legacy drivers
