Is it a fresh install of Windows 7 or is it a copy that has been upgraded from a previous version. Sometimes programs will not be able to run on a copy of Windows that has been upgraded.
I forget which, but one version of CPS even says that it will not run on a copy of Windows that has been upgraded from a previous generation, only a fresh full install.
EDIT: This is what i was thinking of, I found this in the MTS/MCS CPS Readme, the same is also in the Astro Saber,Spectra, and XTS3000 CPS:
System Requirements:
--------------------
Operating Systems: Windows NT 4.0 (SP 6a or higher),
Windows 2000
Windows XP Home Edition (See Note)
Windows XP Professional (See Note)
Vista (32-bit) Home Premium (SP 1 or higher)
Vista (32-bit) Business (SP 1 or higher)
Note: XP upgrade or Vista upgrade from other operating
systems is not supported if the CPS was previously
installed on the old operating system.
Windows ME and Windows 98 are no longer supported.
You may choose to proceed with the installation, but
some features might not be functioning properly.
Upgrading the operating system is highly recommended.
I didnt see it mentioned in the Waris CPS.
Also what Mars said is good advice too
