Licenses is not it registered

I have licenses Bonex because is not it registered

yesterday everything worked fine

Domain : not registered Expires : 25.05.2011

"Remove your current license (if any) from Dashboard -> Settings -> Advanced Settings -> Variables and then re-login into Dolphin Dashboard to register a different license."

I tried a few times,
when I add manually replaced by the message:  The license never expires.

what is the problem?

If I delete the old , when  log off and log back I did not receive any window to enter the license

Please help

Thanks

When you remove the license from admin and log out. You need to log into the back end to be prompted for the license. http://www.yoursite.com/administration/

I tried a few time

Then try clearing the cache after removal of the license. The only reason it would not prompt for a license is if for some reason dolphin thinks it's still there.

Problem solved,
I must uninstall module: Simple Redirect Version 1.0.3 of the harvest-media.com
