can't debug exe file

Hi,

The code below compiles fine with fasm and I can load it into OllyDbg without any problem. However, 7 lines from line 210 are commented ';' out. These lines refer to a dialog resource. If I uncomment these lines I can still compile it with fasm but both OllyDbg and W32Dasm report
Quote:
The MDI.EXE file appears to be corrupt.
Reinstall the file, and then try again.
Anyone any ideas as to what is happening? Confused
Code:
;file mdi.asm
format PE GUI 4.0

include '%fasminc%\win32a.inc'
