Please download the file again and install over the top.

If errors again, please attach copies of your complete log.txt and pinballx.ini files (no copy and paste please). Thanks.

[retrogamer01]

Thanks for the quick reply. Redownloaded and installed with the same issue.  log.txt and pinballx.ini attached.

log.txt PinballX.ini

For a test can you install to a new location / folder and see if you still get the error with just the default databases / media that come with the installer?

Might be a corrupt media file (animated png?)  somewhere in your setup, this might help prove that. 

[retrogamer01]

It works as expected when installed to a different directory with my config.ini file and the default media.  When I move my media folder over to the new installation it exibhits the same behavior.  I don't have any apng files on my system.  I have ~700 tables worth of media though, so it's going to take a while to figure out what is corrupt. I'll start putting directories back one at a time until I find it.

Its probably a jpeg/gif/bmp file masquerading as a png file.

Looks like its one of the core theme files, such as a logo rather a table image.

[Tom Speirs]

Im moving to only supporting apng when files have the apng extension so should be fixed for the next release.

Thanks @Tom Speirs, it's proving elusive but I'll keep looking for it.  Thanks for addressing this in the code.

[retrogamer01]

Spot on, @Tom Speirs.  I was able to isolate the issue to one of my Systems Logos that I added for Pinball Arcade.  Without that file in there it works as expected.  Thanks everyone for helping me resolve this.  I suspect the next release will fix this also, but in the meantime I'm up and playing again!
