Hondata,
With my laptop iCore3 , Windows 7 Proffesional i have an issue with the datalog.The Ecu is a PRA with Kpro III and calibration loaded by the Kmanager 3.2.4 version on a Lotus Exige K20 Swap.
The car run very fine but often when i datalog, the Laptop disconnect the USB port with a Windows error message like as "USB port disconnected, the device can not be recognized".
After this message, Kmanager don't see the Ecu connect..
If i restart Kmanager is the same...
If i restart the laptop, Kmanager see the ecu and i can datalog..
When i have the windows error message, the datalog show as the attached..

Are you using resistor or non-resistor type spark plugs?

I use Resistor spark plug but not the iridium..
I use the BKR7E plug..can is an issue?

You might want to try just putting in some new resistor plugs and see if that has any effect on this.
