I have this project I save into a new version every few weeks to keep some kind of version control and make backups of any previous versions. Today, after an extensive coding session, I tried to run the project and it didn't start. Output window's last message was "Entering main lop" and that's all. Tried to check if there was anything wrong with my code, any potential loops in it, but to no avail. I run the inmediately previous version, saved just a few hours back, and it run smoothly. I coded the project again on this version to try a find out what was the origin of the problem, but there wasn't any problem at all. Previous, but updated, version started without problem. Then I save the working project into a new version, start it... and it gets stuck on "Entering main loop", without even touching the code, or any other resource. The only change was the name of the new project I saved it into. Tried it several times, different names, different folders, but nothing changes. Every new version of the project just stops launching. Anybody has any clue about this? Because I would like to know how to avoid this from happening. Thanks in advance.
