having trouble installing scripts

Hi I got a couple of ad scripts php based

they come with a installer everything goes ok until it's time to hit link from installer to go to admin panel all i get is an error page.

I have got to the stage of getting a blank white page when i type the actual site link in browser but error page still for admin panel

any help would be appreciated

Cheers

so you installed some ad's on your webserver, and get no admin page?
which ad's did you install? where did you get them? what is your url? show the code for the admin page aswell, then it will give everyone a lot more to work with
