Thank you
I realise now your issue with the logo. There is a very slight gradiant over this area of the template which is showing up the edge of your logo. To remove this gradiant try adding the following to the Custom CSS field of your templates parameters...
#container_hornav {
background-image: none !important;
}
Regarding the slideshow module I have added it to the 'showcase' module position. It should now be displaying as it is on our template demo.
