I need some advice and help. I downloaded the GWX 3.0 to my silent hunter 3 several weeks ago. I really enjoy the new scenarios. My problem is this; when l select "single missions" most of them work fine, but several ( 3 or 4) of them function normally EXCEPT the intended enemy doesn't show up! If l select "Career" instead of single missions

, the enemy is never present. I can park a sub on the surface at the mouth of the Thames in broad daylight and nary a DD or aircraft shows up. Obviously something has not loaded right. Any help would be appreciated. Tks
