Help!!! Verisign.php files have destroyed my oscommerce

[dabbuhl]

I have a cart setup with 160 items at:

 

www.flagsdirect.net

 

I downloaded the verisign payflow and followed the instructions for installation. Basically just copy 2 files over to the directories that need them.

 

Now when I go to my website and I get all text as well as when I go to my /admin. I don't get a login, just text. It is like a line from the html was removed and now I just get raw text. I don't know how to fix it and I don't want to uninstall the OsCommerce because I use plesk to auto install and remove and it will remove all the work I have done.

 

I need some help. Someone please help me.

 

What do I do.
