I've tried uninstalling and installing it again but it doesnt help also if I close the notifcation is just keeps popping up and theres around 5 of them, please help.

KarenMichelle has offered this advice in Answers to other people with the same question.  It seems to solve the problem:

Your PC has an invalid registry entry for the Media Player function. This can  happen when you uninstall a previous media player from your PC or a automatic update fails for an existing media player.

Take these steps:

1) Download and install QuickTime from www.quicktime.com. Allow it to become the default player for all it's normal mime & extension types..

2) Perform a clean install of the SL Viewer following these instructions:

3) Start SL and allow SLVoice to run thru your PC's firewall if prompted.

4) If prompted, also allow SLPlugin.exe to run thru your PC's firewall as well.
