I have download SharePoint 2013 since four months ago , I worked on it for one month , then I was involved with other products. Yesterday I tried to login to the central administration but I got the following error:- HTTP Error 503. The service is unavailable.
So I am sure that the 180 days trial version is expired , so I have the following questions:-
If the trial version expired, will I get this error; HTTP Error 503. The service is unavailable ?
If the problem is related to the fact that the trial expired, then how I can define a new valid key ?
If the problem is not related to the trial version, what I can do to login to the CA again ?
