Sorry for the confusion here. OmniFocus uses your iDisk for storage, but we have our own synchronization code. Apple's code isn't going to be able to update the database in a way that OmniFocus is going to be able to understand.

Check the sticky at the top of this forum (I moved your posts to the iDisk syncing forum) for the steps you can use to restore your sync and prevent this from happening again.
