Hi Jim Fogle,
I have edited the second post who show how to apply skins.
For the splash screen it 'll show 2018 version only if you choose my skin but you can replace it manually with the 2019 version you have (located in the image folder)
For unknown reason i can't edit the others post so:
Just unzip Metro & good old days in the folder:
Then Right click in the chord-sheet area
==> display options
Then on the new windows at the bottom left there's a button labbelled "choose skin"
Here you 'll see my skins if you have unzipped in the correct folder .
You can revert back to default choosing simply "default"
Thanks for the links but something is wrong with the second one
