    Oh, Blackberry. I've had you only a week and I already hate you.

    Everything was going fine. I've been syncing my Outlook calendar and desktop with no problems until last night. That's when the Desktop Manager 6 said there was a BB software update. Fine, I did the update. Now my device's address book is empty save for one contact repeated 10 times and the Desktop Manager says the Address Book is not installed. I did a full restore and that had no impact on the device's address book, though it reversed everything else on my BB by about 24 hours.

    Any ideas?

    I'm having exactly the same problem with my BB Tour - only the address book. How do you roll it back to the old version?

    I rolled it back using the Desktop Manager V6. Go to Device/Device Update/ and look for a button that says "View Other Versions." Then just choose the earlier version from the list.

    After the device rolls back, which will take a while, I think you still have to check the box next to Address Books under "Organizer." If it's grayed out, click on "Configure Settings."

    Hope this helps!

    I have a 9550 Storm 2 with nothing but sync issues since and Desktop Manager 6.0. I have spent over 10 hours dealing with sync issues and chasing error 0x80043ac9 which has no clean answer on any forums. I think I am going to do a rollback as well. Thanks RIM for taking a page out of Microsoft's book on testing.

    I rollbacked also. it did not eliminate the address book not installed error for me. I loaded my gmail account and installed my contacts over the air. I now have my phone book back. BB has one unhappy customer here.

    After some playing around, I found that KB23978 as mentioned by DrWeir worked for me. I couldn't use an older backup, as that just messed up my contact list. I also first cleared my contact list completely on the Blackberry before I made the backup, and re-synced it with my outlook afterwards. Here is the link to the KB : KB23978-BlackBerry Desktop Software 6.0 displays address book or calendar as not installed within Organizer
