Hi,
Are you exporting the png to the same folder where the .exe is located?
I making it in a subfolder, does it need to be in the same folder?
It needs to be in a completely different folder, not the same and not in a subfolder. It's stated in the "Limitations" section of the tool's page. I'll make it clearer there.
Gotcha, yeah I was confused. Thanks for the help.
