enabling network: Because your install is not new, the sites in your WordPress network must use sub-

doing a fresh install of wp. enabled Network in tools (modified wp-config.php) but when I go to setup my network I get:

Because your install is not new, the sites in your WordPress network must use sub-domains.

I cannot use sub-domains due to host limitations and want to use directories instead. Why does it say my install is not new? is there a certain order of doing things or a flag I have to clear somewhere?
