Sarah,
Previously, I have the same problem as you. I overcame it by using relative reference whether I need to code referring to directory. My way is to use macro substitution & and system functions SYS(5) and SYS(2003). For example, to open a database mydata in the data subdiretory:
wdir=sys(5)+sys(2003)+"\data"
open database &wdir\mydata

To solve your problem completely, search all codes containing directory and replacing them with relative directory.

Hope your problem can then be solved !

Regards

Harry
