Creating an add-on "product type book" for ZC 1.5

[DMLyons]

Dear DML,

are you 100% certain that you are using the version 0.9.3Beta from Sourceforge? ( http://sourceforge.net/projects/zencartbookx )
I have downloaded the package from there again myself just be sure there is no mistake on my end and these lines are definitely different in the file tpl_product_bookx_info_display.php that comes with 0.9.3 from there?

Regards,
p.

Yes, it's the first installation, but no...apparently, it's NOT 9.3. It's 9.1. Head desk. No wonder I'm having problems. So, I guess the question is... What do I have to do to change from 9.1 to 9.3?
