I did as instructed:

made duplicate store with files from live store
uploaded files from zip
ran zc_install

now the installer wanted to know if I wanted to change the db prefix...mine is already zen_ so i deleted that from the selection to leave as is and it claimed to go through but could not do one file (sorry I forgot to write down the file name)

the store part works to go see, have not gone further than first couple of pages because I wanted to check something in admin.

admin is a white blank page, ran error bug tool and this is what it says:

[22-Apr-2010 01:04:28] PHP Fatal error: Cannot redeclare zen_get_products_manufacturers_name() in /home/xxxxx/public_html/xxxx/admin/includes/functions/extra_functions/my_xtra_functions.php on line 7

there is no such file in there and have no idea what to do since it is not in the zip either

part 2 of question:

found in zip / images/3ds

what are these for since they are not in the 1.3.8 version there are a few other files that i found also but I might have missed reading about them in the docs too...sorry

can you please let me know what to do
