Hi, I have been having trouble with a file in Photoshop. Whenever I try to open the file, it displays a message saying it can't open it because it's not compatible with this version of Photoshop. Except, I'm using the most current version of Photoshop, and I installed and reinstalled it as well. In addition, the file has a size of 529 MB. Is that too big, did that have something to do with why it's not opening, and what should I do about it?
