I got a warning message (added a picture of the warning I got) when opening up Sas Studio. I do not pay for it (it has been free to use, have been using it for half a year at least) Not sure what should I do, because I would like to keep using it and I would like to keep all my documents. Is the SAS Studio I am using just a trial version? What do I need to do? Can I not use it after April 4? or should I just ignore it?
