Hi,

I have a Single Developer + Runtime Free Licence. I wrote a program on my computer that use the opcDaClient. The license is installed on that computer.


When I published that program on a different computer, everything was fine, but after 40 min I have this error "Object Reference not set to an instance of an object ". (in the itemchanged event of the da on the line "e.Vtq.HasValue")

Do I need to uninstall the license from my dev computer and then install on the server? I need help...

thank you,

Mathieu
