Hi kaiser,
If you're having problems with loading errors that means 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 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.
