I have Acrobat 9 Pro and have a valid serial number. I get the following error on startup:
If you cannot see the picture above, the error says "Licensing for this product has stopped working. You cannot use this 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 don't have the disk any more but do have the serial number. I need someone to put a download link on the web so I can download and reinstall. Please help ASAP!!! The support line will not help and said that this is the only way to get assistance.
