Compling Error

Hi all

I have developed one application in MAS. I generated that application but it shows

BOL Generator : : Compiling VBA project Failed. Please check the generated project for compiling errors.

Error UI Generator :: Compiling VBA project failed.

What is the error? Where i can find out the error?

Meanwhile i can't able to open mobile sales application. It shows error "Mobile Started failed".

Anyone help me.
