[Elecraft] K3 ERR BP2 following KRX3 and KBPF3 install

[Brad Johnson]

Installed the KRX3 and KBPF3 modules yesterday and am getting the ERR  
BP2 error message [ No response from KBPF3 option shift registers].

The troubleshooting step in the manual advises to de-install the KBPF3  
on RF board.

Should I simply re-install it and see if the error message shows up  
again  or is there something else I should check?

Thanks and 73,

Brad
