After trying the Trial-Version of Lectora 6 I am using now Lectora International Publishing Suite 6, SP5.The software runs stable without any crash downs but after 7 days it says "...please contact Microsoft..." during startup. Installing the program again didn't solve the problem. By now I discovered two possible ways to use it anyhow:1. Starting the program once with admin-rights gives me again 7 days free of errors.2. Changing the system date to a time within the 7 days period.Both ways are only temporary solutions.Does anyone of you know how to fix it?
