Two recommended options I have found in the following thread:
Reset the Adobe After Effects Preferences:
reset your preferences by deleting or renaming the preferences file that is located in the following location:
\Users[user_name]\AppData\Roaming\Adobe\After Effects[version]
The name of the file should Adobe After Effects 14.x Prefs.txt
or you can try running Adobe Affect Effects in compatibility mode:

Choose Windows 7 as the operating system.
