i was using the 1.7 version and was very happy with it. monday, i downloaded the 2.2 version but really didn't care for the advertising area on the bottom and the player, so i deleted it. now i am experiencing a problem with the 1.7 version. since turning my computer on tuesday;the computer was "warming up" and a box appeared saying that java...._ ._ cannot be found. the shortcut icon is now just a plain icon. please help!!! since tuesday, everytime i turn on my computer the same message appears. any help would be greatly appreciated.
