F90GL & Fortran Power Station

(1)I am using Fortran power station on windows 98. I want to upgrade opengl 1.0 to f90gl.
(2)I downloaded the F90GL.zip from compaq.
(3)I copy the *.lib to the …\LIB, and *.mod to the …\Include, *.dll to the windows/system, and *32.dll to the windows/system32.
(4)when compiling the source code, “Bad module file format”!
(5)I found the format of opengl_gl.mod is fully different from that of opengl.mod

what is wrong? what can I do then?

You may need to upgrade MS FORTRAN power station (4.0 ?) to Compaq Visual FORTRAN 90.
