Dear amrelhajali,

Are you sure that you have opened the NetPro properly? It seems that you have not selected you application correctly. Additionally, make you that you have the correct software installed. if possible, please attach your overview configuration and CP devices.

net pro worked correctly for other projects 

see the attached hardware configuration for this project 

i didnot add the sm module cards

If you look at the first netpro printscreen (32.png) you attached, at the very top of the window just above the text "To display the connection table ...." and below the icons, there is a horizontal grey bar that you can drag down.

Normally this is in the middle of the window but it looks like it has been pulled to the very top in your case.

what did you mean by horizontal grey bar ?

and i got this error 

It is not an error.

Look at where the arrow is pointing in the attached picture to find the horizontal bar.

Or an easier thing would be to select "Window -> Restore arrangement".

wtf um an *** 

thank you very match :)
