For others having issues when updating Shockwave.
symptom BFAHP after splash screen sits on white box cannot use mouse on the square.
here is the steps to help solve it..
goto Adoby and update Shockwave player.
if it fails or keeps asking you to restart,
then go back to the page to install/update shockwave,
Look at the text on the bottom of the screen,
click on the text " Standalone installer"
download, and run, install
and hope it works.
it fixes the broken shockwave for me.
