Try building the example and see if you get the same error. If you get the same error with the example means the obj file might not be linked correctly to the fp file. You can do that by first loading the fp,then going to instrument >> edit , and then use show info to make sure that a obj file is connected to each fp. Also make sure you have loaded all the fp's that the example loads.
