Remove Product_info.php from my address

[hopey]

Hi everyone, I am a complete newbie to Oscommerce. I would appreciate if you would bear with me..

Basically, I would like to remove 'product_info.php' from the following address

mysite.com/product_info.php/dress-code-p-37

I recently installed an ultimate Seo Urls 5 Mod.

[hopey]

Just to specify my problem for your ease. I could use a guide to solve this
