PLX2 corrupt?

[purrvert]

My V1 stopped logging PLX2, just shows open voltage of 3.6v. Using Windows 7 in Bootcamp V7.5.7 build 283. I have an older version on my computer V7.2.7 build 236, When I review the identical log file in both versions build 236 AD2 shows correct voltage but changes PLX2 to LM1. Also both versions add two un-selected PIDS, Ext.AD1 and Ext.Temp1 Thermocouple. I load 21 pids and record 23. Attach far left build 236 center build 283 right pid selection in V1. Anyone seen this before?
One more item. when loading pids to V1 bottom frame of build 283 scan shows generic, vin and operating system 2030003, I select controller and it shows GM-VIN-2030003 but when I connect to V1 it reverts to generic-vin-2030003.
