Today I downloaded the trail version from the QUICK OPC UA.
While I want to do the first steps, the following Message occured. I was trying to connect the textbox to a OPC UA Server!
Run time is over the limit. The license you have (most likely trial version) does not provide valid data after certain time period expires. Note that after the component's process is simply restarted, valid data will be provided again. Obtain and install proper license to resolve this error.
So the application wasn't runnig, how could this message pop up?
