been getting these several times today, been playing the game a few weeks and never had this issue before. if this is going to be an ongoing thing then im done with this game.
try these steps
1. restart computer
2. restart internet either modem router or both
3. delete all browser history
4. remove browser cache
5. uninstall and reinstall browser
it might be worth to check if the game works in a different browser to see if its a problem in the browser your currently using
any further problems dont hesitate to contact me by going to my profile and sending me a message via the yahoo ping box i have set up there.
hope this helps =]
