i set up my account with Cardservice International and i downloaded the newer linkpoint module and unzipped it to find about 15 php files. I am using filezilla to FTP my files to the server. I just have no clue where to put these files to properly install the module. any help ?

INSTALLATION:

The files are arranged in the same structure as Zen-Cart v1.2.x/v1.3.x - Upload them as such.
I really don't understand what that means.

please forgive my noobness , i have never installed a module to zen cart before.
