Starting over

Anybody else having problems with Tiled 1.2.3? I've reinstalled it more than once to overcome this problem but every time I close and reopen it crashes and won't open, forcing me to reinstall it again. On top of that I cannot access custom properties from my tilemap in LibGDX. I also wasted 2 hours just to find out that the render order is always right-up instead of what it says, right-down. I've spent way too much time just trying to navigate around errors so I'm going to start over again and decrease my scope a bit.
