Erik,
I have not moved images in the file folder, changed data sets or introduced/taken away anything in terms of inputs. Nor did I edit them in any way via other software. Fortunately I have another version of the model on the steam edition of RC, and am able to process that fairly quickly for work purposes. I would still like to get to the bottom of this, so please tell me what information would be helpful to diagnose the issue.
Thanks,
