A. There shouldn't be any .part. just .rar
B. Yes it will, the logs will be put in the usb drive, but don't expect logs to be sent back to you cause that doesn't work yet.
C. Yes, you can see the logs on vista, that's what i'm doing. Btw, if you don't wanna use ur super slow xp comp, just use vmware on vista and install xp on it. Hope that helps!
