Cubase 9 Plugind incompatibility

Hi,
I’m in a bit of a trouble and would really appreciate the help!
Up till yesterday I’ve been working with Cubase 8.5 with my TC M40 Reverb plugin (64 bit)
on my Impact Twin Tc Card, - every thing worked well and I was happy,
Today I’ve upgraded to Cubase 9 and the result was that my plugins disappeared and was marked in the “black list”
My TC firmware is the latest 3.61 64bit, win
yet in the Cubase “Black list” it and marked it as 32 bit therefore unsupported

Can anyone tell me how to resolve this issue?
Many thanks!
