Hi, I've been using PremierePro cs5 for months no problems. When I tried to launch it today it isn't working (it was fine yesterday). No windows appear and when I right click on the icon, it just says programme is not responding. I haven't changed anything on my computer since yesterday so really don't know why this is happening. I'm using a Mac Book Pro 10.6.8. I've restarted my computer a few times and made sure no software updates are due, I'm not really sure what else to do as I'm not that knowledgeable about the technical side of things!
Any ideas would be greatly appreciated.
when starting PPro hold down two keys while launching to reset the "definitions".
