Thanks elk, but that didn't work. I did get help from tech support though and the solution is to recalculate customers accounts. Someone else may need this information in future.
As above, most of my entries for January do not appear on income statement or balance sheet. December was fine and everything entered more recently is fine. Income statement for January says "There is no information available for this report." The balance sheet now technically works but includes only recently entered data. The journal shows all entries normally and the entries are in account reconciliation. Help!
