Been using MP15-17. Now when I burn a image file, regardless of what hardrive I save to; after about 20+ minutes of rendering, I get this: "You cannot save temporary files in H:\, it is either copy protected, or is not located on a hardrive. Please select, another directory". All my drives have atleast 100GB of space. Tried 3 hardrives, same result. I'm using Win XP. The files do start, in a new folder on the drive. If I restart, and choose; "to use all files"; the error pops up, right away. The size of video, 3.0GB; it only renders about 601 KB, before it stops. Last week, I tried a dual layer project. which did the same thing. But I got about, 3 Gb of data, before it gave me the same message. Thanks for any help or patch. Tried that; burn essentials file? same problem afterwards..
