PNG Images Aren't Being Found

Hi, on some png’s, I receive this error in the console after Corona SDK crashes:

I’ve tried saving the image as 32-, 24-, and even 8-bit. I would greatly appreciate some help, as I’ve been having trouble with this for a while now. [import]uid: 13174 topic_id: 5046 reply_id: 305046[/import]

Never mind, I finally managed to solve this on my own…
I had to replace ball.png with a file that did work, then, using an image editor, paste in the actual image that I wanted. I don’t know if this was somehow caused by me, but if not, people should not be forced to use this workaround. [import]uid: 13174 topic_id: 5046 reply_id: 16590[/import]
