When I go to reconcile my US bank on Sage 50 it shows that I am reconciled , I process but it does not complete the step. It goes back to the screen as if I never processed. It has happened the last few months, so according to Sage I haven't reconciled since August. I have been trying different avenues to solve, but our year end is coming up and I need to have this figured out. Everything was fine up to August.

Any ideas?? Please.
