Okay, I was playing the game normally on Windows 7. I was almost finished. And then: there was a power surge, the circuit breaker tripped. The computer shut down. I put the breaker back in, turned on the computer, and when I try to launch the game, it DOESN'T start: it just says to close the program and that's it. What should I do?????????????
I completely uninstalled the game, downloaded it again, but it still doesn't start.
(censored) // WHAT
SHOULD I DO?
?

Added after 12 hours 25 minutes
In the end, I downloaded and installed a new launcher, and now it won't let me into the game, it requires some kind of key. Although I played for 3 weeks without it before((((what should I do????????
