Hi Rebecca
This is the kind of problem that you can't fix yourself. I am an "expert" Adagio consultant and I can't even fix it, because it requires special tools I don't have. You will need to send your data to Softrak (or another data repair company but Softrak is the one I would recommend) and get it repaired by them.
In the future, before opening a new fiscal year or closing a year, make sure that all of your accounts have the right account type.
Your other option is to find a backup set of data that is from a time before 2009 was closed, and if you want to go that route, I would have to advise you on the steps to take with that data.
