Cycles importing image as plane

Hey guys, I was trying to import Alpha images as planes in cycles, but when I clicked import, i got an error message, no matter what I did. I was following this tutorial, (, because I needed to put a recycling sign on a bin, and this seemed to be the easiest way. (Also, I have no idea how nodes work, as I am fairly new to Blender…) Any help?


i got an error message
So what did this error message say ?

What version of blender are you using ?
What image are you trying to use ?
Attach or post a link to your blend file

Thanks for the answers guys! It turned out that I was using an outdated version of Blender, 2.63, and when I updated it worked fine. Thanks so much for the help!
