Hey Triton,
If you're having problems with loading errors that could mean you need to clear your flash and browser caches. These errors usually occur when the game cannot read or access the cached files on your system. If they become corrupted or unreadable you'll often experience what you have described.
Please have a look at this news article about clearing your caches ( http://www.wgt.com/news/archive/2010/03/09/have-you-cleared-your-cache-lately.aspx ) and make sure you are performing regular maintenance on your system. Any time you're having prolonged loading times or load manager errors this should be the first thing you try. It's also a good idea to clear caches when we release a product update.
