Help, can't reload HFSS project after simulations

This is interesting! I did a simulation and during the course of the simulation, my display resolution was messed up. However, I let the simulation run to an end and then I saved the project, shut down my system but when I restarted my system, I get the error message "loading project failed". I an stunned at what might be going on, any ideas?
Thanks,
