home link changed – wrong adress

Hi, I’ve started a photoblog with the autofocus theme at this adress http://www.picturelakefoto.se/blogg
The link named “hem”(home, in swedish) now suddenly refers to the top domain http://www.picturelakefoto.se, my homepage, not my blog(and I’m really not proud of the homepage i created). The link used to refer to the home of my blog, the first page of the blog. I have no idea what I’ve done to create this, but I would like to change it back…I just can’t seem to find where to change the adress from http://www.picturelakefoto.se, to http://www.picturelakefoto.se/blogg
Help?
