Had same problems after upgrading to ME.
Loaded 402d patch and most of them gone.
The latest
403e patch fixed "duplicate folders" problem.
Load it, it should help, but sometimes you may get message: "this update is not for your version" -
hkctr is right.
The only way I know, is to uninstall all adaptec products, go to registry and wipe all remaining traces. After that patch may go.
