Dingux worked fine until just now- now when I try and boot it up it keeps saying Failed to load res/wallpaper.png file is unsupported format.

How do I fix this? I spend so long trying to get Dingux working :(

Sorry if this has been asked before, but I cant find a similar post anywhere, thank you!

P.S. I've tried wiping the mini SD and putting the files back on, but still it dosent work

I apologise; this seems to have repaired itself mysteriously after moving wallpaper.png around a couple times to somewhere accessible
