When I click on Quick time player I get "Quicktime player failed to initialize properly (0xc0000008). Click on ok to terminate the application" and I cant use I-tunes either as I get a message saying "Quicktime is not available. Quicktime is required to run i-tunes. Please re-intall I-tunes. I've tried to re-install both but get the same messsages - can anyone help??
