Flash Player fails to install. i have uninstalled the version i already had an tried installing a later version only to find it would not work on the version of mac os x i have. so i uninstalled that and tried to install the previous one that had been working for me reasonably well before i uninstalled it. oh and i have a MacBook OsX version 10.5.8 by the way. so now when i try to install it fails and when i try to trouble shoot i get a message saying that a later version of a plug in is already installed.. how can that be when i uninstalled the flash player and am now just trying to install the same one back on my computer? can anybody help get my flash player to install properly?
