Compilation error ; breakpoint 0*7c90120e

Hi everyone,

I've received a program that seems to work correctly on  windows 7 (code block+fortran)

I've ran it on windows xp (vitrual machine),  i've got these errors.

1)  forrt1: severe 29: file not found, unit 50

I've made some changes in the  OPEN instruction, then  I've got that  new error message

2)forrt1: severe 24: end -of-file during read, unit 50

I've tried to use  debugger and now the error message i get is " user  break point from code at 0*7c90120e"

I've n idea how to fix it;  can anyone help me.

I've installed a virtual windows xp machine  on my windows 7. And i work with developer studio. My code was written  in f90.

Thank u
