Crown RR5700 Error Code 115

Hey everyone!

My RR5700 shows event code 115 which states that the Access 5 software is incompatible

I checked access 5's software PN and it shows "Invalid"

I tried using Crown MSDT to download and update the software but it still says access 5 software PN is invalid after a successful download.

For context, all other modules (access 1-4) show their software PNs which are from the RR5700RM6000V20 package.

Weirdly enough when i select RR5700RM6000V20 from the MSDT dropdown, it doesnt detect the trucks modules.

I have to select RR5700RM6000V18 for it to be able to detect the modules.

But why are Access 1-4 software PNs on the truck from V20?

Is the steering module faulty? Or do i need to force flash everything back to V18?

Sorry for the long post, this is one of our only trucks in the fleet and we need it up asap...

Any help is much appreciated ????
