My newer MacBookPro has stopped working and so I downloaded the game on to my old Macbook white but can't get it to launch. I try to launch it and get the window that wants me to copy my product key and then after hitting Play get an error pop up:
The application LotroLauncher quit unexpectedly.

I am running OS X 10.5.8
Processor: 2 GHz Intel Core Duo
Memory: 2 GB 667 MHz DDR2 SDRAM

Any suggestions or is my operating system too old and I'm screwed? Help much appreciated.
