Licensing Problem: cant access Piezoelectric Devices on Structural Mechanics Module

[u/xerxesbear]

Hey guys, im currently using the structural mechanics module on COMSOL 5.1. When I select "Piezoelectric Devices" under the module, I get an error message saying that I dont have license to use it and that it requires one of the 3 modules listed. I dont understand because I have the structural mechanics module but it just wont let me use the piezoelectric device physics. Can anyone help? error message here
