CST - error 50093

Error 50093:Hi, I am new to Antenna magus, I have downloaded student version and trying to use it for the first time. When I click "design" button with my design parameters or without my design parameters, I get error 50093. I have tried different types of antennas but all of them are giving me same error. I have tried to understand error log files but could not understand them. Please see files attached.
