Wierd things after installing FS9.1

I upgraded my fs9 to 9.1 and wierd things started to happen to my addon sceneries. My Lago Monaco scenery start having trees floating in the sky and crash my Apache. My very nice HK scenery suddenly have the victoria harbour flashing like a Christmas tree. Then the coast line of my vancouver+ scencery suddenly becomes straight like a ruler not to mention Central Park disappeared from my Manhattan scenery. I have no time in trying to find out what other things went wrong with my 160+ addons. I just uninstall the upgrade. I read the readme on fs9.1 and they said that some addon may not work with the upgrade but it seems all addons doesn't work instead of just a few. Anybody has similar problem with moving from 9 to 9.1?
