I have this issue too. The itch client needs proper version numbers on the game files to work correctly. Right now it can't figure out your game's files, so it's throwing a message saying there are no compatible versions. This affects new installs as well.
I'll take a look at it and bring it to my software guy when he's available. Thank you both so much for letting me know this happened! I promise we'll do our very best to get it working for you ASAP
