First let me apologize if this has been addressed prior. I searched and could not seem to find my problem

I just installed JROX and everything went well, no errors at all. I got to the end and clicked the button to login to my admin panel and I get a "page cannot be found" error.

If I type in http://www.skintastic.com/affiliates/admin/index.php I get a "No input file specified." and nothing else.

Anyone have any ideas why this is happening ?
