Jeff,
LiveCycle forms only work in the "full application" (i.e. Adobe Reader, Adobe Acrobat Pro, etc.) Browser based "add-in" versions of Adobe Reader don't have the muscle to render LC forms.
You will need to disable the Chrome Acrobat Addin, or if I.E. is your default browser you will need to:
Settings>Manage Add-ins>Select "Run without permission"> Find Adobe Reader and set to "Disabled".
If things are configured correctly, the OS will be forced to open all .pdf files in the Acrobat Application installed on the computer.
