If reconciliation gives you a run-time error and closes the program, go back in and open Bank Reconciliation.  Uncheck Payroll Check import and try again.  If that works, you will need to manually key your payroll batches into the reconciliation, and you will likely have to re-enter all your outstanding transactions.

I don't think EasyAcct has ever been fond of being on a shared server, but that seems to be particularly true now.  Moving data files to our local hard drives speeds up processing and report printing times considerably.
