I recently got minecraft_server1.7.2.exe I ran it once successfully and then decided to mess around and extract it with 7zip. After going through and deleting several thousand files that it extracted, I tried to delete the minecraft server exe but it just said calculating time and discovering items. when trying to run it again, it just froze and then refreshed the taskbar, which it normally does upon boot up. Please help me. I haven't found any helpful article anywhere on the internet so any help will be appreciated. Note: it is this file specifically that has this problem. I am able to delete and run other files.
