Castleville Not Loading Again. Adventure World Still Overgrown.

I finally got Castleville to load after about three weeks of complaining to Zynga Support, it just started working. It worked for about a day then started taking longer and longer to load. Windows was suggesting some updates so thinking it was my computer I installed the updates. Now I can't get back into Castleville again. Why does this happen? Zynga games fail to load even if I haven't made any changes to my computer software or upgraded my browsers. Then when I contact Zynga they tell me to upgrade browsers, Java and Flash Players and these things still don't fix the problem. Any suggestions?
