I started using pooler cpuminer v 2.3.3 yesterday and it works. Today, it doesn't. I have no idea what the problem is, when I open the batch file, the minerd file disappears.
This is my command line thing: http://pastebin.com/DyqstLrn
UPDATE: The thing that was causing the problem was Malwarebytes Anti-Malware. It works fine now, thanks for every one's support!
