PlugNPay not showing up

Hi I am trying to install the PlugNPayAPI (CreditCards) and have run into some issues. I have installed it and am receiving no errors; however it is not showing up under payment modules. I am using the most recent version of ZenCart. Thanks in advance!

From the Posting Tips box which shows above the Reply box when you click Reply:> NOTE: When making a new post, be sure to include relevant information such as:

• What version of Zen Cart are you using?

• Has your site been upgraded? When? From what version(s)?

• If you've upgraded, HOW did you upgrade? (official upgrade procedure or an automated script from your hosting company?)

• What plugins/addons have you installed? When? Where did you get them from? If your problems are payment-related, what payment module(s) are you using? If it's shipping-related, which shipping module(s) are you using?

• HOW did you install Zen Cart? (upload via FTP and run zc_install, or a one-click install from your hosting company? (one-click installs might mean you don't have enough information about your site/server to make customizations easily))

• What version of PHP and MySQL is your server using? (See Admin->Tools->Server Info)

• WHEN did the problem "start"? How does that compare with other events of your hosting company, changes you've made to your site files/addons, or your admin settings, etc?

• If this is your first store, have you tested all aspects of transactions before going live?

• In what ways is your site customized or different from a brand new uncustomized install?

• Please post your site URL* so we can take a look at it. This is especially important if you're encountering display/layout problems, so the problem can be seen directly.

• Include the name of your hosting company (not their URL).

PHP Version: 5.3.21 (Zend: 2.3.0)

Database: MySQL 5.0.96-log

Zen Cart 1.5.1
Database Patch Level: 1.5.1

This is the only add-in I have installed.

I have installed itPlease explain exactly what you did to "install it".

partinrl:

it is not showing up under payment modules.Do you mean it's not showing up "in your Admin"? or not showing up "during checkout"?

If it's not showing in the Admin, then you either didn't upload all the files to the correct folders, or you uploaded them backwards.

Thank you for your help!

For anyone else who runs into this issue, make sure you install it in the correct order as the read-me instructs.
