2 things
First you only have 3 posts and pentti said you need to have at least 5 useful posts.
Secondly do you have a SRL ID, that is different than your forums user name. If you don't have a SRL ID than go here to get one
http://www.stats.srl-forums.com/
After you get a SRL ID then start the script called Setup SRL and at the bottom of the form that pops up once you run the Setup SRL script you can enter your SRL ID and pass and then the SRL ID and pass you enter into there should be used for any script including pentti's awsome script.
This is where the Setup SRL script should be.
