Tinytask invalid recordings

Basically, i recorded a macro with tinytask, and it works fine. I save it and everything go right. However, when i open the saved macro, it pops up with a message saying "This file does not appear to be a valid recording. Load anyway?", and It does save my clicks, but it doesn't save my keyboard presses, or sometimes it will preform an action that wasn't in the saved macro. Anyone know why this happens, and how to fix it?
