This happened to some others as well, I havent identified what the problem is yet since I cant replicate it.
Someone earlier with this problem reported that debug export worked on his machine instead.
Maybe you can try this link out instead and see if this works for you? Thanks!

Debug web have the same problem but windows one works. Also I've seen that the game is been updated, I was able to mine two block this time but than it crashed.
PS. With the latest ver. I tried starting the game with Windows 7 compatibility and as administrator and it works!
PPS. Also two things I wanted to get rid of some weight and by discarding materials the weight did not drop unless I mine another block and when I run out of stamina I can still continue mining.
