Your mod is not coded correctly. The code has to be more than syntactically correct (no errors in Eclipse), it has to do the right thing at run time.

Specifically mod loader tries to load your mod, and your mod class fails to be Constructed.
Most likely thing is that you failed to implement all the abstract methods. Your mod class can not be abstract. Abstract classes cannot be constructed and are just raw materials for extending into other classes (like BaseMod.java is meant for).

Remove the abstract key word from your mod's constructor and fix any errors that creates (i.e. implement any missing methods that are still abstract).

Would it be possible to find out how exactly you got it to work? I seem to be having trouble with the same error (InstantiationException).
