I'm releasing a new version to fix this bug, sorry for the inconvenience.
In fact it's an incredible story of bad luck... I'm using an exe packer (UPX) to save about 10MB in file size, I've always done that and I've never had any issue with it.
All of a sudden, for an unknow reason, the exe stops working after it's packed, I've discovered it after releasing this version, and that's what happened with the user in the other topic. The app stopped working not because there was a problem with the code, but because of that packer issue.
I don't know why life is so hard with me those days, I'm a black cat, it's bad luck after bad luck
