JanHermstad I am sure we can help you here! RBL seems to have forgotten that we all started off knowing nothing, and none of us developed our skills by paying someone else to do the job for us! You have paid a chunk of money for your software, and these forums are here so that you can get help with it.
When running the install script, you have to enter some information so that the script can work out where it is installed, and what settings it should use. Many of these are explained in the installation script, and some of them are filled in for you! So I expect there are just a few things that you are stuck on, so if you are still stuck, let us know exactly what you don't understand.
Paths and URLs
A path is a server path from the home directory to the directory that you are installing the script in. For example: /home/username/public_html/your_script/goes_here If you do not know the path to your public html directory, ask your hosting provider.
A URL is the web address that you type into your browser to get to a specific location on your web site, and it should begin with http:// For example: http://www.yourdomain.com/your_script/goes_here/
Anything else you need to know, just ask.
