I've been using spriter for about 2 months. First month was fine, didn't have any problems. Now i've come back to it after a bit of a lull from doing any work in Spriter and I can't get the workspace to load up without glitching. I've tried resetting a fair few times but every time it starts up like this.. http://i.imgur.com/m6182pc.png as you can see where the main window for where the workarea should be is glitched and is showing the root folder of the project. Any ideas how I can fix this? I'm using Spriter Pro edition b8_1 on a macbook pro.
