Fatal Error in Photo Shop 1.3.3

[KWH]

I just installed Photo Shop 1.3.3 and when I am logged in as Admin and try to check out I get this error message: "Fatal error: main() [function.require]: Failed opening required 'include/gateway.inc.php' (include_path='.:') in /var/www/vhosts/haesslyphoto.com/httpdocs/mine/plugins/photo_shop/photo_shop_checkout.php on line 24"  I have checked my files and gateway.inc.php is located in the include folder where it should be.  I have set up the gateway to go to Pay Pal.  If I am logged in as a registered user or not logged in at all when I click the check-out button I get a blank screen.

I was using 1.3 prior to today without issues.  I uninstalled 1.3 and deleted it from my server prior to adding 1.3.3.  Any advice?

Thanks in advance for your time.

I figured it out.  I neglected to move the gateway.inc.php file from /plugins/photo_shop/include to /include.
