[Elecraft] P3 problems

[Alan Grant]

I recently attempted to down load the latest firmware for my P3, and now
have a problem, the P3 says "Boot loader checksum failure, ready to
download. However the computer cannot find the P3. So now I do not have,
what I come to rely upon my ability to see what is going on around the
frequency I am on.

 

I have tried what the manual says but I cannot get the  computer or K3 to
talk to P3, what do I do now ????

Help please
