Okay

I was stupid enough to plug it into the computer without installing it on accident, and then when i tried to install it, my laptop doesn't read it, and when it does read it, there is no installation box. Also, when i tried to open the folder to see if there was any way to install it in the disk itself, my computer always freezes, as if it doesn't wanna install it. Any suggestions? Do i need to get a new one? ...It was actually a Christmas Present... but yeah.... DX
