License error

Just recently all of Be.as users when conecting to the system receive this message, after clicking OK the message appears again, and you have to click again OK, and the system let you access and work normal. Does any one know how to solve it?, we haven't change anything and this message is new.
No updates applied, no network changes or firewall or antivirus change.
Thank you very much.
Oscar.
