Can't load Unity license

Hi, I installed Unity v4.5.51f1 ( according the the license file that I created ). I could reach the license server so I manually created a license. I then connected to unity to get a license for free use. I got the file but when I want to load the license I can’t select it and so load it. What can I do ?

If you have tried manual activation, you’ve probably got an license file downloaded to your machine. Very occasionally that gets an XML file extension added to it by your browser, which knows it’s an XML file. That can stop the Unity editor from seeing it when you go to the folder you downloaded it to. If that is the case just take off the XML file extension.

Thanks Graham. It was that issue ( with a .txt added ). For some reason when I first removed it, it didn’t took it into account.
