License stopped working

Hello. The license key you are using (S/N 1999352962) only covers versions up to 5.69. I do not have explanation as to why it worked with an earlier build of 5.70, but it does not matter.

Your company has a newer license key (S/N 1999350186) which covers 5.70, so just use that one.

Best regards

Hi,

I'm getting an error:

ERROR:
Not allowed to run by the license "Multipurpose". You might be running a trial license, and the version of the software you are using is obsolete. To resolve this problem, a) obtain a recent version, or b) ask for an evaluation license key, or c) install a license valid for the current version.Product information follows. Component name: "QuickOPC", license IDs: "Multipurpose", version number: 570, release date: 02.12.2022., trial validity: 397 days, option expression: "EasyUAClient".Context: 1 dropped license(s); S/N 1999352962 (release date covered 23.07.2022.).

The version of the nuget we are trying this on: 5.70.1352
Before it was working on version 5.70.1053, but that's just a minor version change. What could be the reason this is not working now?
