Compiler errors on Tutorials

Hi there. I am new to Unity3d, coming from an Unreal engine background. I am exploring Unity tutorials and examples and encountering a number of compiler errors with these packages. Specifically the networking example; http://unity3d.com/support/resources/example-projects/networking-example.html

Are these tutorials created for an older version of Unity? And if so, where can I download an older version–or better yet—can I expect a usable tutorial in the near future?

I would love to continue moving forward with this, but I’m not learning much looking at compiler errors. Thanks for your help.

You need to fix the script by yourself! I do it here and works fine! All you need is to type “var” before the variables and will solve it all! Use de console to help you.
