Please help me

I have been having a lot of trouble with the Sims 2 lately,in fact,I recently decided to stop playing Bon Voyage and go back to Seasons,I thought that everything would return back to normal,silly me...............
Anyway,this morning I created my nice little custom neighborhood and plopped two CAS famillies within it,I was already having trouble getting the game started but then I started deleting the accessories cache before I started it and everything started running smoothly again,well,that is what I thought..................
Anyway,right away I noticed the light blue screen with the spinning hourglass showing up again,first when my Sim was on a community lot,and then in the neighborhood view when I went to save,after I made sure that everything had saved I quit the game and went back online.after about an hour I decided to go offline and play again,first it took three times to start the darn thing again,and when I entered the game my custom neighborhood had been deleted!:hmph: It had been replaced with a neighborhood called weather?! Anyway,as soon as I entered "weather" the game crashed,I have a ton of custom content in my game and a few hacks(JennFlower's teen woohoo,swim naked,naked water wiggle and woohoo naked,I was wondering if it was the hacks or the custom content causing all of my trouble? I have been playing the Sims 2 for over a year,in fact,when I just had Pets installed I had one game last 6 months,and I didn't have one hack or custom item installed.I was wondering if there was someone out there who could explain to me why I am having so much trouble,I am seriously thinking about uninstalling the game for the tenth time this week and deleting all of my custom content,if it meant that I could actually start playing again
