It is great to hear everything is working fine.

One thing to keep in mind is when you do receive a message like that again, rebooting the workstation always helps because QCW sometimes thinks there is someone else trying to access the program. Also, there could be a resource file that is stuck or corrupted and rebooting will clear the connection.

When you ran the Data Integrity Check the error ?24 of 25 cheques printed? and there were only 24, you should of clicked on the ?Rebuild? and it would of fixed any errors. After the errors are corrected run the Data Integrity Check again.
