All of a sudden, Quickbooks 2009 would no longer email invoices.  It started failing with the error “Quickbooks cannot connect to the remote server because part of your company data is currently in use.” In addition, I could not print to a printer nor could I even open the “Printer setup…” menu.

I found this tech article about the problem and proceeded to follow the steps to make the PDF converter compatible with 64-bit versions of Windows.  I rebooted my PC and when I re-opened Quickbooks, I could get into the “Printer Setup…” menu.  However, I got the error, “You cannot print directly to the QuickBooks PDF Converter. Try using QuickBooks Save as PDF menu option.”

I was about to go look this up, when I checked the printer setup options again and restarted QuickBooks. When I restarted, everything worked fine. I’m not sure what that was, but it seems to be working fine now.

Hope this helps.
