http://www.casinosidan.info.se/ has pagerank. Did you take the content that was there and move it to casinosidan.com? If so, that could easily have confused the bots into thinking they were mirrors and they will try to not index the second one until they figure out the first one isn’t there.
And how long has the site been up? You don’t have a ton of links to it, so a it could take a few weeks.
Also, your internal links point to http://www.casinosidan.com/index.html change that to just http://www.casinosidan.com/
