Actually, I think you're right. Hexview is full of TForm and TButton. It's a RealBasic program, and the main exe is importing some RealBasic plugins.

My problem is that I have no string references in wdasm/ida. Also, registration dialog have 3 buttons: Quit, Demo and Proceed. Proceed button is active only if you enter the correct sn. So, there is no way to enter a dummy sn, press Proceed, and then bpx on usual breakpoints. I try to locate this nag screen, but the program is full of call xxxxxx followed by jz/jnz/jnb xxxxxx, and you know how much this is annoying for a beginner :-(

Anyway, thx. for your kind reply.
