Firewire problems with windows 10 and audio interface

Hi everyone
Im an amateur musician composer (I do have a day job in architecture).
I've joined this group because I'm having major problems with my music setup after building a new pc for using VSTi virtual instruments / orchestral sample sets. I use a firewire audio interface (motu traveler mk3) but since upgrading my pc it has been crashing whenever I connect the motu to the firewire interface. I understand there is an issue with firewire compatibility with Windows 10. I had some issues with my previous set up, occasional bluesecreen / crashes, having to reset the motu as my default audio interface every so often.
Windows seems to have a driver which should be compatible with the PCIe firewire card (a Qnine, which is compatible with the Texas Instruments chip standard) but I still have this problem.
Does anyone have any advice? It's driving me up the wall, I've spent hundreds on this and just want to get back to making music!
Pleas help
thanks

Thanks firebeard. I've ordered one of them in case that's the problem. Cheers!

In addition, I used the built in Win 10 firewire driver, the "legacy" is no more and not needed.

Just following up. Has it been resolved (and what was the fix).

No response. I'm going to assume its been resolved.
