I get the same "warning" but all is working fine here , I guess it has something to do with the frame rate linking.
But I don't have your Error , "CCLiveLink_Blueprint_C is not valid" , why "C" ?

Also, when you transfer the Character via LL , you have to select your CC Character and tick the CC Setup afterwards to convert the shaders , when you import via fbx you don't have to do that.

Did you try "Apply Blueprint To Selected Character" under "IClone Live Link" for the Character that you imported via FBX ?  Do you get the same Error then? 

cc auto is 1.04 and is installed and enabled
livelink  is installed 1.12 and enabled 
this was all updated then i transferred the character into unreal using the live link
then i get this and it also does not transfer the shaders properly i had to go and manually update them

yes its installed its just out of the screenshot 2 more icons to the left of live link
but thanks

The CC Auto Livelink is either not Installed or Disabled in the Plugins 

I might be wrong but your screenshot does not show the Auto Setup 

Version 1.04 (Release Date: 2020-06-08) installed

yes and yes

Are you using 4.25 and is the CC/Auto live link turned on?

i get an error when linking in the unreal live link 
it says the node get subject data in the cclive link blueprint is depreciated does anyone know how to fix this
thanks
