I am new to Slingbox. I bought a used Slingbox pro. Connected all the wires(I think properly) and when I went to my computer nothing happened. My computer does not have a CD reader. Called support and was told the Co. does not support my model any more. So what should I do now? Where can I find the proper software to download? Should I download that software on all my computers.(having one in Canada and one in the USA. Where can I find a step by step instructions how to install the devise and how to use it properly?
