I work for a business that wanted to try revit so we decided to get the 30 day trial of revit 2013. I made an Autodesk account after about 15 days so i could render in the Cloud. After i exited from revit and tried to open revit again it promted me with a "activation required" message and my 30 day trial was cut short. Cant figure out what i need to do to be able to use the program for the rest of my trial period.
Hi @mcollins291 and welcome to the Community!
By design, once a trial expires there is not way to extend or revive it. However, you can visit the Virtual Agent and download another version of Autodesk Revit on to your machine. Another option would be to download the 2013 on to a different machine. Apologies for the inconvenience!
