Rebecca:

There are a lot of places your May 2010 transactions could be.

The normal process is that you must retrieve them from the subledgers to the ledger. Normally when you open the Ledger you will get a message to this effect. In Ledger try 'Retrieve Subledger batches' under the maintenance menu.

As you still have fiscal 2009 active look for the 'Next Year' button (this will be fiscal 2010). Open this to see if your transactions are sitting there un-posted.

Beyond that, and given you inexperience with Adagio, I suggest you cantact your Adagio dealer for assistance. If you don't know who your Adagio dealer is you can contact Softrak directly for this information.
