Hello moore7299,

Welcome to the SH4 forum.

The Silent Hunter forum is changing things around and you happen to post right in the middle of the switch. Could you try posting in the new Silent Hunter Tech site and provide the following information -

Could you tell us what version of Silent Hunter you are running.

What are your computer specs?
