@chinamaxim,
Are you saying that you’ve reformatted your PC?

No, I don’t dare to format it, I’m afraid of losing the reward for bravery. I have an idea, I am going to upgrade the 32-bit window system to 64-bit, but I dare not do so, because I am afraid of encounters like netizens in the community.

@chinamaxim,
Do you have a verified browser wallet?
