[Elecraft] KPA500 Remote control problem & question

[Jim - KE8G]

Hello All,
Well, Murphy raised his ugly head this weekend during the ARRL SSCW contest.

I am operating remote and everything was working fine; the K3 radio, KTA500 tuner, and KPA500 amplifier.  I was monitoring things via the Elecraft software for the tuner and amp.  I was on 80 meters and saw a HI SWR warning come on the KPA500 software, but not on the KAT500 software.  I clicked the "Clear Error" area and then received a Comm ERR.

The KPA500 software seemed to freeze and the only thing I could do was terminate the program.  I re-started the software and it gave me an error message saying it could not make contact with the KPA500.  I closed all the running programs on the remote PC, and then did a re-boot.  All is working well except for the KPA500 software.  I keep getting an error message telling me the KPA500 remote is not running and it can't find the amp.

Any ideas that I can do via the Internet?

Thanks in advance,
