The latest CS Captain II 763ER v1.0 release is listed as P3D5 compatible, so just purchased & installed it on my P3D5.0.32.3523 ("HF2") system.  All works well, except that as soon as hyd are on, the stab trim runs away, ANU.  White band all the way nose up.  Stab config warning on takeoff, and airplane isn't controllable in flight. 
I can drive trim back nose down with the yoke thumb switches (or the alternate stab trim levers), but immediately the trim starts moving toward full nose up again.  Stab trim cutoff switches have no effect. 
Checked my CH yoke elevator output with FSUIPC6 - entirely normal.  Not present with P3D5 another company/FSLabs aircraft. 

Can't find any earlier reports of this from P3D4 users.  Has anyone else experienced it?  Guessing it might be a v1.0 or P3D5 related problem. Suggestions on how to resolve it?

Images of trim indicator and horiz stab position attached.
