Tiled - Isometric Map Problem

I’m not sure if this is the correct forum to post this, but it does say Engines, Libraries and Tools.

Let me get to the point, I am not sure what’s wrong with me, but I simply cannot understand how do you place tiles in isometric tile maps using Tiled Editor. When I create a new map it asks me for map size and tile size. I know the tile size, so I enter the correct tile size, but still the rotation (if you want to call it like that) isn’t good.

I would provide screenshot under image tags for forum, but I thought it was too large, so here’s link: http://oi57.tinypic.com/ayrc4g.jpg
