I basically have a virewer now. I paid for and have had the bility to create and edit PDFs along with forms and all of the other features. Now nothing at all - I delt with support on making an adjustment a while ago and thigs worked then stopped again. 

Any ideas?

Do you have a subscription, or a perpetual license? In both cases, you should be able to do some "license maintanance" from the Help menu in Acrobat: You should be able to activate/deactivate the software or to log in and out of your Adobe account (depending on which kind of license you have). Does that do anything? In general, for licensing issues, it's best to deal with Adobe's support (as you've successfully done in the past). The only thing I would try is to remove the Acrobat installation using the Acrobat Cleaner(https://www.adobe.com/devnet-docs/acrobatetk/tools/Labs/cleaner.html) and then install from scratch.
