Does anyone know a fix for the popup, "an unknown error occurred while accessing (file name)? It happens when trying to save files. I have tried with the parts saved locally and on a network but it seems like the parts are corrupted somehow. I have recreated the parts and eventually the same popup occurs. Any help is greatly appreciated.
