I just installed AutoCAD 2012 on a new computer because my other one was 4 years old and could not handle AutoCAD and Photoshop being open. I need to install the AutoCAD 2012 Service Pack 2 but the digital signature out of date and I can't install it. Now I have an unstable version of AutoCAD. Does someone happen to have an original file or can the people of autodesk make the file useable?
