chnage 50 day license to unlimite license

I bought the 50 day license and that is what is on my admin (advance setting-->Dolphin License Code), i now have the permanent unlimited license and want to upgrade to the unlimted. I delete the 50 day license and pasted the unlimited, but whenever i save, i get the old license# in the dolphin license code field. can someone help plz. Thank you

I have the same problem. I got a free license and it's registered to my domain. We got the unlimited license, but how do you register that to your domain so it will be accepted in the installation?

I had a similar problem like this before and was told to delete the old license and save. Then go back in, add the new license and save again. It worked after. Try it!

Logged off and cleared the local cache. All of a sudden the admin logon page looked different and I was able to empty the field. New code is now accepted, although it didn't remove the "powered by" footer. Am I to understand this take a bit of time to sync with the license server?

After you have managed to get the new permanent license code in you need to log out and then again clear your cache and it should work.  It did for me...no more ads.
