Simucube 2 Ultimate Firmware Update Problem

Hello, just received my SC2U today. After getting everything connected and booted up I am having trouble with the truedrive software. I downloaded the latest version but I keep getting the error in the image attached.

I tried updating firmware from control panel>device manager but it says I have the latest firmware already installed. But truedrive says I need to update firmware for me to continue.

I tried uninstalling and re install. No luck. Also installed a different version of truedrive, no luck. Disconnected all SC2U power/cables and still no difference.

Any ideas?
Thank you,

Stop button is released as well. I saw that was the problem for some others.

Solved, didn’t know you had to twist the stop button to release it!
