Loading a 2.49b in 2.57, i cant see the nodes!

So, i recently got 2.57, i found it is amazing, but as i try to open my projects that were done in 2.49b, i cant see the material nodes anymore, i have selected the right material and object, and the “Use nodes” option is enabled, but all the nodes are gone, can someone help me with this, what can i do to see the nodes in 2.57?

I still see them in 2.49b, but no way in 2.57.

There is “Load UI” in the Open File window. Maybe unchecking this helps. 2.49 UI layout in 2.57 is messy.

Thanks man, it worked, you’re awesome!
