I keep receiving the attached error "Content is not allowed in prolog." when I try to save a certain model file. I've tried clearing all solutions and meshes, resetting the solvers, compacting the history, deleting unused nodes, parameters, functions, etc...
It won't let me save the model; I'm not sure if it's related but I've had another error message pop up every time I compact my history that reads "Unkown Frame. -Tag: ".
Any help with these errors would be great, thank you.
