Thanks for your help so far dave, I have sorted the problem out now. I have 2 hard drives installed on my computer, and ended up with the mecanique folder on D: and mpasm on C: or something, so I think the program was looking in the wrong place for the INC files. I now have a set of flashing LEDs in front of me, so im off to a good start and very pleased.

Thanks very much Dave
