Adobe acrobat 9 pro installation/licensing issues

Question

I installed my licensed copy of Acrobat 9 on a new Windows  7 system.  Acrobat launched but would not open files and shuts down on attempt. Message is "Licensing for this product has stopped working" with subtext "You cannot use the product at this time. You must repair the problem by uninstalling and then reinstalling this product or contacting your IT administrator or Adobe customer support for help."
I doubt any of you have a solution, so I simply remark on what transpired as a warning and complaint:
1.  I went to Adobe databse and found that a patch was provided to correct installations/licensing problems on windows 7.  I downloaded it and installed per instructions.  It did not resolve the problem.
2.  I uninstalled/reinstalled several times. no resolution.
3.  I called customer support and was outsourced to someone who knew little and first sent me to a kb article having to do with 'expired licensing' even though I clearly informed them that the message and the fact had nothing to do with expired licenses.  They finally referred me to kb405970 on "Licensing has stopped working".  I tried all of the applicable solutions (methods 1-6) and none of them worked.  Now I will have to wait until tomorrow (though I had pressing work to do today) to contact support again.  I fear I will get another outsourced tech who knows little and wastes more of my time.  Such is Adobe's way of supporting paid and licensed product users.
I understand and sympathize with Adobe's wishes to protect its products from piracy.  However, I expect and paid for a product which works on major and supported operating systems like windows 7. I also understand that if MS or Mac put out a new OS or version, it may require certain adjustments or updates on Adobe's part.  What I do not understand (or have patience with) is that 1) Adobe failed to provide a patch that works; 2) that it then sends me to an outsourced customer service tech who didn't have the knowledge to correct the problem and gave me the wrong information to begin with*. What I finally got was the kb article with a series of multi-step instructions for several methods, none of which worked.  This is an unprofessional and unethical response to those of us who have paid for our product and expect it to work under reasonable conditions in a supported environment.  This is not an acceptable good-faith effort to resolve issues for which Adobe should take full responsibility.
If any of you do happen to have a real solution (or had a similar problem) do let me know....
*The first thing the outsourced tech wished to do was get onto my machine via a remote connection, before anything was tried other than giving them the error message and have them provide me with the wrong information. It became clear that this person had less knowledge than I do (which isn't saying much) and there was no way I was going to permit a clueless techie to crawl around in my machine and fiddle with settings.  That is simply asking for trouble. I'm perfectly capable of opening panels and following instructions myself. DC should be the last thing tried; not the first.

Answer 1

Bill,  I tried as you suggested - installed every update from 9.1  through 9.3.4.  The 'license not working message persists'. The only change was that now Acrobat will not close and must be forced to shut down from the taskbar menu.  I appreciate the suggestion though.
Called Adobe (Manila) again, within the hours given on their contact page for installation and licensing issues, and was told "It's Sunday, nobody here can help you".  Finally, after an hour of hammering got them to get me a supervisor (their script says to tell the customer there "Is no supervisor available on Sunday"  -  Finally the "supervisor", Alvin, suggested I need a new serial number and left me on the line while he called someone else to get on. Cameback and informed me that he couldn't get one, I'd have to call Monday (how's that for having solutions?)  Result: wasted more time and had more delay on my project.
Conclusion:  Adobe has become obsessed and 'piranoic' about piracy and licensing to the extent that they put that first and client/customer needs second (if that).  After reading a lot of online 'Adobe Sucks'  forums, I'm inclined to believe Adobe is shooting itself in its own foot and is not going to be a reliable method of presentation/document transmission in the future - service and support is an integral part of software and other concerns such as piracy or licensing need to be transparent to legitimate users.  Sad that they spend so much time on this, when they need to be fixing real problems.  As well, these outsourcing Philipines companies are poor substitutes for good support - they are so scripted and obsessed with regulations over solutions that it is clear that only the most persistent users will get anywhere with them.  As a frontline of contact with after-sale clients, they are going to cost Adobe a lot of potential business in the future, whatever their short-term savings.  Too bad. Adobe used to be a leader in the market.
Next round:  Calling Manila again this am. to be continued...
