Rapid Rig Modular V2 support - Rebuild Rig error

Hi,

I'm just wondering if RR Modular V2 is still supported. I have an error when I tried rebuilding the rig (after I repositioned the proxies). The error message is: ... line 22290: No object matches name: ControlRig

Please let me know if this is something supported and fixable.

Thank you so much
