I regularly play Songpop on facebook but suddenly Shockwave Flash keeps constantly crashing. (Pressing the 'reload' bar achieves nothing.) What can I (safely) do?
You've not told us which device you're using. The following instructions assume that it's a Windows computer:
Uninstall Shockwave Player (via the Control Panel and then 'Add/Remove Programs' or 'Programs & Features'). Restart your computer. (That's important!). Reinstall Shockwave Player from here:
