That seems somewhat strange. If you can provide any information about your system (your operating system, processor, RAM, etc) and the version of the game that you downloaded then that would be greatly appreciated. I can pass along this information to the Love2D team and see if they know anything about what's going on.
Thanks, only other thing I can think of is whether the program is the 64-bit or 32-bit build.
Also, if you want to see more specific information, from the settings go to System -> About and you should see a bunch of system information, including the "System type" which would probably be the most relevant.
