First of all, welcome to the forum, rainbow_six. We're glad you could join us.
Obviously, you need to unlock before you can do anything else.
This thread tells you how to do that.
Secondly, it looks like the first thing the spider in running into is a 404 error - page not found. Is there a link to some page on the start page you've designated that is broken? Try fixing that and see what happens.
I'm not sure if this will correct everything that's wrong, but I hope it helps.
