Usually this IOS image works just fine, but i just tried to load a 3725 router and it didnt work and im getting the following errors

Server error [-3200] : unable to start VM instance 'Ghost'cygwin warning:

CYGWIN environment variable option "nodosfilewarning" turns off this warning.

Same, using GNS3 1.0 release

Make sure you have a correct path to your IOS image.
