Fatal Error with Column Layout Mod

[traders]

i installed the mod following the instructions and am now getting this error:
(mod column layout / grid layout for products listing)

Fatal error: Call to undefined function: zen_get_generated_category_path_rev() in /home/web2easy/public_html/includes/modules/design/product_listing.php on line 209

I copied the sql patch and ran maybe i was unclear on those directions but I took everything from the column_layout_grid.sql file below this:

## The following can be run via phpMyAdmin, or by Admin->Tools->Install SQLPatch:

## The following is used only to remove this mod:
#delete from configuration where configuration_key in('PRODUCT_LISTING_LAYOUT_STYLE','PRODUCT_LISTING_COLUMNS_PER_ROW');

and i think I was supposed to take ALL of that text and enter it. I ran as one patch in the admin tools install patch.

Should I try running the patch again and this time take all of the code in the sql file?

Not sure what to do now to fix other than reinstall zen.

think i found part of the problem. I must have downloaded the MOD for version 1.3.8 and needed 1.3.7. Never ran sql patch before so I'm not sure if I need to:

a) download 1.3.7 and redo everything

b) reload zen and start over (ugh!)

or should I just upgrade my zen at this point to 1.3.8 (not sure that would work either)
