Crealoaded SEO URL's 4.0 fix required

I purchased the CRE SEO URL's 4.0 script from [login to view URL] to add to a customers site. I have installed and followed the instructions but the script doesnt seem to be working. There are no error messages mod_rewrite is supported by the web host and Ive installed the .htaccess file(s) as per instructions. This is probably going to be a very quick fix for someone who knows what they are doing. I have a budget of $30 for the fix and I will need an explanation of what the problem is to save my own sanity I can send the script over to you if you need it
