These files are from my system, they should work with most systems, 
but if they don't You'll just have to delete them.

Check through all the driver files under 
Control Panel / System / DEVICE / driver file details.
If a file name appears in brackets, it's missing.

The files included in this zip file are, 
(Configmg.vxd) - (ntkern.vxd) - (Vdmad.vxd)
(vcomm.vxd) - (vdd.vxd) - (vflatd.vxd) - (vmouse.vxd)

Windows substitues a generic driver file called vmm32.vxd for these missing files.
