I just got OF and OF for iPhone (which I use on a 16GB touch), and I can't get the sync to work. I had it working on one Mac the first night, then I tried it on another Mac too and got this message:
"Unable to synchronize database with server.
Unable to read document.
No root transactions found in “https://idisk.mac.com/emiratesmac/Documents/OmniFocus.ofocus/”."

Then I tried it again on the first Mac where it did work and now it says the same. I still have all the data I've entered on the first Mac and the Touch, but if I can't sync this with another Mac, and basically move OF over to it (my main work machine), then I'll be very disappointed.

Any advice? I've looked through threads here but not found anything that was helpful.
