Movie: Barbershop and error: "Doesn't start with Nav pack"

Help guys.....when I try to strip the Subs and Languages, I get "VOB invalid. Doesn't start with nav pack" error. What is this?

This was an error in some earlier versions of IFOedit. Are you using 0.95?

LWDARLING: Thanks for the response. I was using both .95 and .94. Don't know what it was but the problem seems to be resolved. I found another issue specific with my computer while using both .94 and .95: I have to manually make a destination directory in Windows Explorer and then go back into IFOedit, press the "dot" and point to the new directory I manually created in Explorer. Kinda weird but as long as the end result is a DVD movie without menus, unwanted audio streams and subs, I can live with this quirk.
