Hey everyone! Hoping someone can help out here. I am doing some slide presentations using Flash Player (I know, but it has to be this way). Previously, I would extract the file from a zip on to my desktop and it would just open the presentation. Ever since 10.10, I have been receiving the error shown in my attachment. Last year I had this same issue, and managed to find a workaround that involved on right clicking the file, choosing "Show Package Contents" and then copy/pasting something from inside the file somewhere else. Try as I might, I have been unable to find these workaround instructions again and I am running low on time. Hoping someone in here might have encountered the same issue and be able to offer some help. Thanks in advance!
