Issues with catagory url re-writes with simple seo url addon

Hi there,

My website was working fine with simple seo url on, then also of a sudden when I click on the catagorys on my website it took me off my site to a random website. This was with the simple seo url on, when I turn this off the catagory goes through to the products on my site??

So for example:

previously - http://aaronspromotions.co.uk/pens
now is - http://aaronspromotions.co.uk/index.php?main_page=index&cPath=57

Its great it works without simple seo url on but it means my url's look messy and all my articles with links to pages in my site are now no longer working.

Hope that makes sense? Any ideas what is causing this?

Thanks in advance

My understanding (no direct experience with it) is that SSU uses an .htaccess file to direct its rewrites, so this may have gotten changed. It's obviously not something that should happen, and if it did happen and points to other actual websites could only be due to a hack.
