SP1 resolved the issue. It bombed every time without it. As soon as I installed it YAM ran like a charm :)

Thanks for the help!

I copied it to C:\ and manually tried to start it inside the command prompt. As soon as I hit enter it crashes.

Same result.

Does yam require Win 7 SP1?

Yam.exe crashes as soon as I run it.
