How to stop shortcuts from opening in Reader instead of Acrobat

My employer has a subscription to Adobe Acrobat. For years, I've used this to combine PDFs into one document or convert documents to PDFs using the right-click shortcuts in Windows Explorer. Starting this morning, attempting to use these shortcuts opens up Adobe Reader and gives me the following error message:

"You are currently using the free Reader product. You also seem to have the more functional Adobe Acrobat installed on your machine. Click OK to launch Adobe Acrobat."

• Clicking okay opens Acrobat, but it doesn't perform the action I attempted through the shortcut window.
• If I attempt to perform the action through the shortcut window again (with Acrobat open), nothing will happen.
• If I attempt the action manually in the Acrobat program, it will be successful. But I would like to be able to use my shortcuts again because it saves much time.

Is there any solution that will stop my shortcuts from trying to open in Adobe Reader?
