Hello Reesetibm,
We're sorry for the trouble you had with Adobe Reader, there is a setting under Edit > Preferences > Trust Manager > Automatic Updates > Load trusted root certificates, make sure that this box is selected.
You may also try the suggestion from Adobe Reader DC crashes for certified PDF's
Try repairing Adobe Reader from help>repair installation, reboot the machine after repair. If the issue still persists, remove Adobe Reader using Acrobat cleaner tool Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Reboot the machine and install the latest version of Adobe Reader from Adobe - Adobe Acrobat Reader DC Distribution
Adobe Reader 11 is old and out of support product and the security updates and patches are not available and this may be the reason you are getting the error message.
install the latest version of Adobe Reader and check.
let us know how it goes and share your observation.
Thanks,
Anand Sri.
