Time&Billing is still version 8.0, which is why this doesn't work and still loads the Ledger 8.1A program, as Andrew described above. When Time&Billing 8.1A ships, then Ledger 9 can be loaded from the Adagio menu there.

It sounds like the loading of Ledger 9 from Payables is now working, which is great! As the shortcuts are all correct, now everything should be in proper synch.
