Beamer License Invalid
Hello, Try this Patch: https://macupload.net/6y2/Beamer_Patch.zip
Put Beamer 3.3.3 in Applications folder.
Open the Patcher and press Patch and open Beamer App (It may ask you to install Xcode Tools you must do this).
once Patching is done try open Beamer.
If still asks for license close Beamer and open the Patcher again and Save a license file to your downloads folder.
Open Beamer and open the license file you just saved.
This is what worked for me.
Tried your patch but when it try to install xcode tools it says software is no more available on the server
