Cardset loading error messages are uninformative.
I find that cardset loading error messages, usually caused by either failure to load image file, or bad config, are quite uninformative, oftenly leaving cardset maker clueless about what he did wrong.
And that is generic message for all cardset loading errors.
Can you provide a couple sample cardsets that would trigger this error?
Just try to remove an image from cardset and try to reload it in PySol. You get the same message, regardless what file was not found.
The error wasn't being caught, so I added an error check, which leads to the message that should be displayed.
Though I should probably set it up so a cardset with a missing required card image just doesn't get recognized.
I think, attempt to load cardset with missing image file should output error message like "Failed to find file ####" so cardset maker can correct this by putting in necessary file.
