Hello!
It is I TestAcc02912919 but you can call me Yuki.

If your game keeps crashing make sure you have the following downloaded:
Microsoft DirectX Here
And
VC++2015 Here 

This might fix the problem. 

If your game still crashes even after downloading both of the programs feel free to post the log file here so I/others can see what the possible issue might be.

The log file can be located in the "terracraft" folder under "logs"

Hope this helped!
-Yuki
