Normally, no, when you download a file which isn't corrupted, it will not become corrupted by itself, so I highly doubt it's because of a corrupted file. Mind sending me that file via PM so I can test if it works with my printer? If it doesn't work, the file is probably corrupted, if it does work, then obviously it's something else and we need to find out what that is, but first I want to test out that file myself.
