Check for updates not working in 9 pro

Question

I am running Acrobat 9 pro on a Vista machine. Acrobat appears to have been malfunctioning (bates numbering is not working properly), and I uninstalled (and deactivated) Acrobat, and then reinstalled it.
After reinstallation, I used the check for updates feature in the help menu to update from 9.0 to 9.2. But now every time I run Check for updates from Help, nothing updates. I get a dialog that there is an available update, and then an icon System Tray appears and a process is active for AdobeARM.exe. But nothing ever happens-no update. I then force close the process from the task manager, and still no success in getting Acrobat to update.
What can I do? Thanks very much.

Thank you for your rely. Here is the more detrailed info:
1. I pulled down the Help menu and chose Check for Updates.
2. A dialog appeared that said an update was available; I clicked on the button that indicated I wanted to download and install the update
3. Nothing further appeared onscreengiving my information or choice, but an incon then appeared in the system tray for the installer.
4. Hovering over the icon does not pop up any status information. If I click, double click, or right click on the incon in the system tray nothing pops up, and nothing appears. At that point I get absolutely no response.
5. If I go to task manager at that point it shows the active process AdobeARM.exe and gives no indication of it malfunctioning. But nothing installs and nothing downloads and nothing happens.
6. If I then pull down the Help menu and chose Check forUpdates again, I get a dialog that says the updater is already running.
7. All of this occured immedaitely after I reinstalled 9 pro.
I hope this additional info helps. Thanks very much.
