the big call >> mov eax,01 ret

Hi!
Most of people knows that a lot apps has an important call that the program uses at start up and during the registration routine. A simple mov eax,1 ret solves it,....nothing new.
Recently i've had fun (and got won,too) with an app called word2picture. It's protected by execryptor and its classical big call hides his code with tones of loops, decrypts,bla,bla..which made me give up. I know that the piece of cake is there...but you get absolutely tired looking for the two lines of code that really matters. I was wondering if there is a magical way to find it.

PS: i'm not interested at all in getting a crack for this app. When I want an image from a doc file, i save as... web page and take the jpg file directly.
