Using OF 1.1 rev 2775.

Everything was syncing fine. Until it wasn't. Now I keep getting an error message:

Unable to read document.
No root transactions found in "https://idisk.mac.com/xxxx/Documents/OmniFocus.ofocus/".

So then I read that syncing in MobileMe was easier so I went there. But I think it's still looking in the prior director? Maybe?

Is there any set of instructions anywhere? I keep seeing that it's "really easy" in MobileMe. Oh really?
