Problem after transferring kma's to second laptop

[bryant]

I copied my kma songs folder from my main "show" laptop (internal HD) to my backup laptop that uses an external HD. I had done this several times before without incident. This last time I transferred files, then "built songs database" afterwards, I closed the computer, but upon starting up the laptop shortly afterwards, a "DrWatson "message came on the screen and said windows detected a problem with explorer and wouldn't let me continue. It asked if I wanted to send or not send the problem to Microsoft. I was not online at the time and did not send. I know my next step will be to send, but at what result?

Can anyone help determine what could have begun this strange series of events? Can hoster in any way "trip up" the operation of windows?
