Hey folks, I've come across a problem only recently in transferring Premiere Pro CS6 projects from Mac to PC.
I've been working with a client for about a year on a project that they have been working with on Macbook Pro's (OSX 10.8x and previously 10.7x) that they transfer to me on external drives (HFS format) which I continue to work on on my Windows 7 PC with CS6 (using Paragon HFS to utilize HFS drives).
This has worked fine until recently (and I can't remember if the switch to 10.8 happened before or after this) but all of a sudden when I try to open any of the projects they deliver to me I get the "Project Appears to be Damaged" error.
I don't think the project is actually damaged since it can be open on my Macbook Pro, and all three of the units they have.
I wonder if the issue came up with 10.8 (we are using AVCHD and 10.8 changed the way AVCHD is handled by the operating system)
I understand I can probably just import the "damaged" project into new project but it would be nice to understand why the issue came up.
I don't know the answer but I'd blame 10.8! It's not that it's bad... it's just *way* different underneath where it counts. Can you try to open the project on a 10.7 machine and re-save a copy as something else? If the new copy opens on your Windows machine than 10.8 is probably the culprit. If it doesn't... then it must be something else
I do think it is most likely a 10.8 issue as well. I'll see if I have a backup startup disk with 10.7 on it somewhere and give your suggestion a try.
