Why cant I get Happy aquarium {game on facebook} to play on my computer

I have played it before on my computer but now it locks up. I have Vista operating system other internet games play. the game plays on other computers at library and at work computers. I am not computer savy on what is going on I know enough to mess it up more please help in simple language

Well I dont know the app but if it is use by way of installing it then maybe uninstalling it and then re-installing it. If it is a web application then you may need to clean up your temporary internet files and temp folders. Use the disk clean up by right clicking on local (go to my computer and right click on hard drive), then left click on properties, you will see disk clean up or something like that:) if none of that works then go to facebook and post your problem their and someone will now how to assist.

well then how do u get 2 play it onthe computer cause its really fun

how come I cant play a game on facebook
