Hello,
A few days ago I started with stackz. Program is great, I really love it. But for some reason I have to completely format my hdd and reinstall windows with all software. When I installed stackz all worked fine, program started without any problems. Then I restored my words file from backup, tried to load it... and stackz crashed. After some investigation I found that when you have an undefined language in words file stackz will crash. I already tested stackz on 4 computers, but without success, behaviour is same.
Well, problem is not annoying at all, the solution is simple. Just recreate all languages which are used in words file and crash will no longer occur.
Thanks for reporting!
A fix is implemented, it will be released soon.
This is fixed in Stackz 7.0.
