This is almost certainly your local network issue or local firewall / anti-virus software issue. Please make sure you don't have any anti-virus software blocked DriveHQ FileManager.

You can also try to reboot your PC see if it fixes the problem.

If you still cannot get it to work, please use DriveHQ FTP. For more info about DriveHQ FTP, please visit: http://www.drivehq.com/ftp/
