Did you follow the installation instructions ?
Did you configure it all properly ?
Doesn't the maker of the software offer support ?
Go to the admin interface and make sure it's configured correctly.
If it has a way to clear/flush/delete/whatever it is named it's cache: do that.
For the rest: to be honest with help from a generic forum, you're unlikely to get this fixed: you either need help of people who're used to deal with this exact software package and/or somebody with hands-on access.
