550 can't check

I have read all of the things reguarding to this issue and nothing has helped so far. My FTP server allows up to 50 connections so that is not a problem. I have tried with both regular and alt FXP. I have set the error stuff to ignore. Nothing works.

Nevermind. For some reason SmartFTP thought I had a quota of 0. I just restarted my server and it worked.
