Photoshop will not open any PNG files. Every time I try to open a PNG it says not a PNG file. I have tried with numerous files, including files that I know to be PNGs and the same error message always pops up. I know the workaround where I can open the file in MS paint and resave it, but I pay for Photoshop and it should be able to open simple files that it's meant to work with. I also have updated Photoshop to the most current version to no avail.
