Bug??
Hello, my name is Reno and I have played minecraft for a while now. Unfortunally something went wrong:a little while ago, my dad downloaded something on our computer. By doing this he let virus in (not totally sure of that) wich caused the computer to crash. So, we bought a new empty hard disc. I tried too download it again. No issues here, however opening/starting the launcher was a difficulty.

Normally, the launcher would just start, but the game said;

I have tried all options in downloading, but none of them worked. I have no idea what triggered this bug.
