Hi Arturo,
The log in failure could be caused by 1 of several things, but the most common is a firewall. If you were logging in before with no problems I would suspect that you may have received an update to your security software.
If that does not get it going please contact us directly so we can look up your account to be sure it is not a problem this end.
We are available Monday through Friday, 6:30 AM to 6:00 PM Central Time. You can email us directly at support@iqfeed.net or we also have a live chat function available from our web site
