Blackberry - Calendar not syncing

Desktop app shows Calendar (not installed):

"When opening Organizer within BlackBerry Desktop Software 6.0, the calendar shows as not installed."

Blackberry has a temporary workaround:

Perform the following steps:

1. Back up the data on the BlackBerry smartphone. See KB23680. 
2. Delete all data and applications from the BlackBerry smartphone using the Wipe Handheld option. See KB14058.
3. Restore the data to BlackBerry smartphone. See "restore data' in KB23680 link above.
4. Connect the BlackBerry smartphone to the computer and open the BlackBerry Desktop Software.
   Calendar (not installed) will no longer be present.

I suggest the following steps (insert plenty of reboots of your PC...not just restarts, but full power down reboots). Also, it is advised that you be logged into the PC on an account with full admin rights. Further, under Vista, use the "Run As Administrator" option for everything.

1) Remove your device OS update package from your PC (add/remove programs)

2) Cleanly uninstall the RIM DTM software:

• KB02206 How to perform a clean uninstall of BlackBerry Desktop Software

3) Get a fresh download of the RIM DTM software:

• http://na.blackberry.com/eng/services/desktop/

• Choose the version that is newest and (if applicable) compatible with your PIM (if you are synchornizing via USB):

• KB12268 Applications supported by BlackBerry Desktop Manager for synchronization

4) Download (to your PC) a fresh copy of your device OS package from your carrier:

• http://na.blackberry.com/eng/support/downloads/download_sites.jsp

5) Install DTM to your PC

6) Install (also to your PC), the device OS package

7) Start the organizer configuration over:

• KB17022 How to configure organizer applications for synchronization using BlackBerry Desktop Manager

Hopefully that will get things going again.
