Hi there,
To talk to someone from Adobe support:
- Go to Adobe.Com
- In top right of screen click Sign In
- User your Adobe ID and password that is registered against your Acrobat Pro membership/license
- At top of screen click Support link, and select Contact Adobe

- Under "1. What can we help you with?", click on Adobe Acrobat Pro.
- Under "2. What type of issue are you experiencing", click on Licensing and activation.A number of 'self-help solutions' will appear, but you should also see a BLUE button 'Show me my contact options'. Click the Show me my contact options button.

- You should now see "3. Would like to contact us?" and below that a 'Chat' and 'Phone' option.

- Click the Phone option and the "3. Support - Phone" option appears with a phone number listed below it that you can dial.
NOTE: the phone number will vary depending on what region / location you live in. Most important is that you Sign In (step 2), as without a sign in I believe the phone option will not be available.
ALSO in the meantime you could opt to install the FREE Adobe Acrobat Reader, so at least you can see the PDFs and review them, that might be a work around to use for now?
