I have to use PSSE 34 student version. I want to add a composite load at one bus, but when I have loaded the .dyr, the software shows me this error. The reason is that I'm using the student version? Could you help me to solve that? thanks

 Generator models use:
  CONS        1-   160
  STATES      1-    60
   VARS        1-    10

  Shared Load Characteristic models use:
   CONS      161-   293
   ICONS       1-     2

  Return to Dynamics terminated--system model requires too many VARS
  Unshared Load models use:
  STATES     61-   141
  VARS       11-   302
  ICONS       3-    98
