My neundo 12 licence expired. what might be the problem?
Same here, ‘No valid licence found’ except it is valid, and can be seen by the elicenser (which i don’t think is relevant for me now anyway but thought i’d mention).
Did you launch the Steinberg Activation Manager, login to your account, and see if it’s become deactivated (possibly because you activated it somewhere else, or just haven’t connected in a long time?)
