Application Error has occurred: All options for Air Source Heat Pump have disappeared

edit

Hello, I keep encountering errors every time I try to access the options screen for ASHP components of my BEopt model. I am still able to run the model and obtain both hourly and annual aggregated results. I am encountering the same problem as this user's post here (includes screenshots): http://beopt.nrel.gov/node/941

Any help would be greatly appreciated.
