Hmm interesting,
The steps i took for your templates where no different then the ones i took for just any old template off the internet or one i would create from scratch via photoshop.
My steps:
download template to local file, for me i use xamp so i loaded into the xamp file, then defined the site with the local server. After that i just created the editable regions for the templates topnav links, content, footer links.
Created a preset for the template in the site sculptor preset manager and gave it a menu.
Then when i ran it through the site sculptor it gave me that error at the very end when i went to finish.
Interesting you've never heard that error? any ideas how to fix now?
I will try deleting all my templates and trying again as would like to get those stuffed into my preset manager for a later date.
THanks
