Newtork Theme - Permalinks and Menu drop shadow

I cannot use permalinks with this Theme. When I change to permalinks the site shows as 404 error.
This has been posted previously without resolve. Seems there is no straight forward answer.
Suggestions on what I need to check is good please.
Second problem: how do I turn the drop shadow off on the main menu??? Very undesirable to have this and I don't want it on...searched through many many many style sheets but when looking at this with firebug it appears to be a built in function or some sort with Superfish v1.4.8. I just need to know how to get rid of this don't want it or need it but the theme options do not allow me to "turn it off" could someone give me some direction on how to get rid of the drop shadow on the navigation.
