Reason 5 on Macbook Pro.

Hello, I recently bought a Macbook Pro and I am trying to install Reason 5. When I start to install it, I drag the reason logo to the applications folder and it saves it there. once I open Reason, it asks for me to insert the Reason 5 DVD; Once I do that, it begins to install the sound banks, there are two of them, after it installs the first one perfectly, it starts installing the second one but halfway it stops and says that it is unable to transfer the sound bank (error -36) or something like that. without the sound banks, I cannot use the program. Anyone have any suggestions?

thank you very much!
