I recently installed CS6 to my 2008 iMac. I'm running OS 6.8. When Premiere pro wouldn't work I tried to do some wacky stuff by deleting some third party plugins from the quicktime folder in the library. Premiere Pro is destroyed and I'm thinking whatever I did in the quicktime folder is why it has messed up my application. It won't even open up at all when I click it. Can anyone help me?
