Login Timeout

Hi all.
I've recently installed FOP2 version 2.26 for a 64bit CentOS (fop2-2.26-centos5-x86_64.tgz)
This server has a FreePBX installation, but I cannot login. The login screen appears very well, but when I introduce any extension, regardless if the password is right or wrong I always get the "One moment please" and after 16 connection to the server retries I get the "System is not available right now". I followed all the steps from the setup guide.
If I run "./fop2_server --debug 9" I can see al the messages between FOP2 and Asterisk via AMI. I can see the retrieval of all extensions states, even the SIP trunks:

Flash Operator Panel 2 - No valid license found. Demo Mode
