Pokerdan: you need to specify where ft is installed in the options (which is usually c\throttle).
Vdmsound also has to be installed on the same drive as q+e.
Try running throttle.exe manually, if it doesnt run then the problems with your ft installation, not q+e. Any further problems post on the help section and ill try and help you.
Oh and dual-bootings not worth it really, much easier to use vdmsound, having the disks partitioned in fat32, is just one disadvantage of dual booting...
