i dont thinks its your computer since its a browser game..Im pretty sure you can play this on a computer running windows ME.
It can be 2 things. Something is really slowing down your internet connection, which causes webpages to load to slow.
Or it can be the internet browser that your using. Or both examples put together.
If more then one person is using your net, it could be a bandwidth problem. caused by people watching streamed videos or movies. or playing high rated internet games.
If its your net just unplug your cable or dsl modem and your router if you have one for about a minute and plug it back up and see f that works.
I use to unplug my modem and router then shutdown my computer for 2 minutes, then plug the dsl/cable modem up first wait 30 secs then plug up the router wait 30 secs, and turn comp back on..and that resolved all my problems
