Hello, if you got the new launcher, you might of got this: "Game ended with bad state (exit code -2147483645)" or "A fatal error has been detected by the Java Runtime Environment" or... your game crashes and it says "deletion upon exit" Don't be scared, i know how to fix this!

Now, if you're getting any errors, all you have to do is follow these steps:

1. Right click the launcher and hit properties.

2. When the window opens up, go to "Compatibility" tab.

3. Check the "Run this program in compatibility mod for:" and select "Windows XP (Service Pack 3" in the drop-down box.

4. Go down to "Privilege level" and check "Run thsi program as adminstrator" (NOTE: YOU HAVE TO BE THE ADMINSTRATOR ON THE COMPUTER FOR THIS TO WORK)

5. Hit apply and exit out of the window.

Thats it! it should be working like a new car! hope you like this and it helped you!
