I just experienced the same problem as David. I am in financial reporter and tried to open the payables module and got the following error:
Version Compatability: Your current version of Adagio Payables is not compatible with the version of Adagio Ledger database you are currently using. Complete compatibility information can be found at http://www.softrak.com/appcomp.php

So then I asked my coworker to attempt to sign in and she got the same error.

This is not a "one-off" error. We have replicated this error several times over the morning.

Is there a "fix" that Adagio can provide? It is not feasible to have other users locked out of the program while one person is printing or programming a financial statement.
