Hey, I had reset my Laptop few days ago, but now wanna play Pro again. I register me with an new account, download winrar and the game. When i want to join any server, i cant connect to the server. My other account also cant connect. I restarted my Laptop and downloaded the game again, but it doesnt work. Could anybody help me? I think i need to download any program again, cause on my phone it works, so it hasnt to do with the game and not with my accounts
