Not sure how much you're trashing, but you may need to trash the save files that's created in the flash player save directory and not just where you have the loader located. The flash save directory is a little troublesome to find but I eventually found it with help from google. To save you some time I'll paste in the directory for me:
C:\Users\[Username]\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\VVD9RSS2\localhost\Users\[Username]\[Loader Location]
Replace [Username] with your username and replace [Loader Location] with the folder where you keep Loader.swf. The files you'll need to delete have a .sol file type.
I hope this helps you and anyone else having the same issue. When I updated from 8.8 to 8.9 I saved the 2 versions at different locations while renaming Loader to the version number, so I didn't encounter this problem myself.
