Not to worry mate, it is probably just me, probably hard to teach an old dog new tricks, at least you got through to me how to fix the import table, I just coudn't see the instruction that moved the first item to the iat.
Here is the error message generated by the unpacked .exe:

00410994 /$ 68 30100000 PUSH 1030 ; /Style = MB_OK|MB_ICONEXCLAMATION|MB_SYSTEMMODAL
00410999 |. 68 AC094100 PUSH RegDefra.004109AC ; |Title = "Warning"
0041099E |. 68 B4094100 PUSH RegDefra.004109B4 ; |Text = "File corrupted ! Please run a virus-check, then re-install the application."
004109A3 |. 6A 00 PUSH 0 ; |hOwner = NULL
004109A5 |. E8 D24FFFFF CALL <JMP.&user32.MessageBoxA> ; \MessageBoxA
004109AA \. C3 RETN

And references to this command:

Is getting rid of this error message more complicated than just nopping all these calls?
