Hi,
I already read and followed all instructions that I have seen on FAQ about this, disable antivirus, verify cache etc, but still nothing.
It takes some seconds authentificating the ticket and then this appears on a white background:
Error: Could not get a Steam Auth Ticket. Please ensure Steam is running and that you are logged into Steam. Then relaunch this program.
You may find additional information on the FAQ or at the forums. If you post a new thread asking for help, please include a link to your log.

Here is the log:
Thanks.
