Hello! Can someone help me with a problem I'm facing in MIKE 3? Specifically, I'm a doctoral student and I'm working on the hydrodynamic motion in a lake in Greece. I've set up all the details and when I go to run it to find the results, it displays the message " The application runs in DEMO MODE" No entry for the requested module found. What means despite I have student license for my Phd through my school? 
Thans in advance

Hello to all dear  Mike members. I have a few questions and would like your advice.I am a PhD candidate on"Hydrodynamic motion in a lake environment" and I have an academic license touse the program MIKE 3 FM I have started several months ago learning the programwith the help of the manuals and some videos on youtube. however, I find thatboth the available videos and the learning manuals are missing (several teachingsteps are missing). Also with the help of the company representative in mycountry (Greece) I tried to have access to self paced course (free of charge)but durung my efforts of logging in with the licenses of my University, finally,nothing happens. Is there any chance to be provided by the team of MIKE DHI anyreliable doc for learning right the software?  I would appreciate any help.
