I converted a java ejb module to .NET and worked out all the errors except 1.  The error message says "Cannot create an instance of the abstract class or interface [name of class]. Could someone suggest some reasons why this would be happening?

Is it a class or an interface?  You cannot instantiate abstract classes or interfaces directly.  For interfaces, you need to create a class that implements that interface, and for an abstract class you need to create a class that inherits from the abstract class.

Also, can you post the Java class declaration and the C# class declaration?  Maybe something got lost in the translation.

Turns out it was none of the things you suggested.  The problem was that I couldn't use an abstract class in my situation.  Thanks for your assistance though.
