Up2stream pro to ACP work Bench

Hi,

I have Up2stream Amp and Up2stream Pro - Multiroom Wireless Receiver Board. But non of these are connecting to the ACP bench Software.

I have also used Up2stream Mini- Multiroom Wi-Fi Streamer Board in my last project and I could easily connect the boards to ACP Bench for all my tweaks.

Am using Audio Codec Processors Workbench 2.21.14
Is there a version change? do I need to get a new version of ACP bench?
Do I need to upgrade the existing ACP Bench Software?

Need help! how to connect to the Up2stream Pro to ACP Bench, as my project is stuck.

Thank you

Hi guys any Luck with this.
