Try putting in the:

SET PATH TO < >
and
SET DEFAULT TO < >

and in the <> put in the path where the data is located in the start of the program

VFP gets confused often and tries to look for data in the home directory where your code resides, but putting in these commands usually helps.

Also look at the setting up a configuration file these are some of the many options you can put in. (located in the help drop down).
