Sorry if I have answered the same as others; I haven't read all the answers. If the quilt shop is still there, contact them
and see if they still have the pattern and get the missing pages. I got a pattern and pages were missing; it wasn't 6 years later, but I went back to the shop and they gave me the missing pages. Or if they don't have them, see if the pattern maker has them. I have gotten them from the designer too. You paid for the pattern, you should get all of it.
Some patterns need a little tweaking anyway.....but if you are a beginner, that is hard to do. Good luck getting all
of the pattern.
