Hello Amber,
We're sorry for the trouble you had with Adobe Reader, please reboot the machine once and then try running the Adobe Reader as 'Run as administrator', you may refer to the following Adobe article for the steps Run an Adobe program as administrator | Windows 7, Vista
If the issue persists, run Adobe Reader in compatibility mode, look for the Adobe Reader's shortcut>Right Click>Properties>Compatibility>compatibility Mode>select the box which says 'Run this program in compatibility mode for select Windows7/8'>click on Apply>OK.
What is the current version of Adobe Reader installed? To identify refer to Identify the product and its version for Acrobat and Reader DC
What is the version of the OS installed? Is any security software installed? Is it a personal computer or an office computer?
