Unity3d Crash error (Mono.dll) with NetworkView

Hi, all and thanks for your time.

I was creating and testing scripts about multiplayer and Unity crash always when I use one button and always if I have the Network view.

NetworkManager: http://pastebin.com/kQ3iQMkg

Menu: http://pastebin.com/4MTbRj9D

These are 2 of the scripts, and it's all okay i think that the error it's in Unity and I uninstall and install 2 times with the newest version and the problem perhaps.

Always the problem is Mono.dll

(I'm not english, so sorry about the words) PD: If you need more informatión, I will give you it, thanks.
