topic AutoCAD asking me to register but won't accept any code given in AutoCAD Forum https://forums.autodesk.com/t5/autocad-forum/autocad-asking-me-to-register-but-won-t-accept-any-code-given/m-p/5743950#M319576 Every time I open my AutoCAD 2010, I receive a notice telling me to register my product and that I have 14 days till it stops working. I have had this since 2010 and have been getting this message for the past two days now.  I tried to use the old code but it won't take, so I tried to reregister and use that code, but it still won't take. I have tried this four times now, with different codes, but no success yet. I am receiving emails though telling me that it is activated and registered, but I when I open AutoCAD the activation screen still pops up. When it rejects a code it gives me "error #0015.111".  Am I going to have to uninstall AutoCAD and reinstall to get this to work, or do you have another idea.
