Ok the driver is not installed or not installed correctly.
First thing to try is re-download Mach from the downloads page and install it again over the top of itself.

Have a look in device manager and see if the pulsing engine (driver) is there.

If that doesnt help then maybe try the specialdriver.bat that you will  find in the Mach folder.

What does the Frequency say?
What Kernel are you using?
Can you try rolling back to SP2 in XP as I have seen people having issues with SP3.

Looks like windows service pack 3 there is some kind of issue I cannot uninstall it , the box that says click here to remove is not there ?
 But it is listed ?

Ok thats relarively close on the frequency so not sure why the driver test is so bad.

Maybe doing a system restore to a point before you insatlled SP3?
