MFDeploy Question on Error received when erasing application

I just tried to erase Storage and Deployment from my Fez Spider.

I am using MFDeploy Version

I am receiving the error shown in the attached MFDeploy.Gif

Any ideas what is wrong and how I can correct this?

As a note:
I changed from version 4.1 to 4.2 firmware yesterday (I use both versions but I have only one Spider)
I have performed a ‘repair’ on all Net Micro packages found.

My Spider appears to be working but who knows.
