Acrobat 9 Pro quits after launching?

Question

I have had Adobe Acrobat 9 Pro installed on my system for years. Suddenly it is giving me a message "Licensing for this product has stopped working.

I have uninstalled and re-installed the software and am having the same problem. This forum says there is no phone support for this product. What do I do?

When you ask a question you need to provide some basic information

Mac or Windows, and EXACTLY which version of the operating system?

Recent Mac AND Windows operating systems have been known to cause "odd" problems

Are you using a computer Administrator account with full read/write permission?
