It appears InDe needs to verify the license with your servers when it opens. I appreciate the reasons for this, however there are times when network services are down and the verification/confirmation process is not possible.
It would be nice if you could add something like a time stamp so it would only be needed periodically. Perhaps every 15 - 30 days. That way you can still protect the license, but allow work to continue in the event of a network connection issue. Nothing is a 100% and there may be better ways than a time stamp, but it is something that needs to be considered.
