@ Brian - I did a complete uninstall and then re-install; same errors with Curve Create.
@ Roy - Yes, my printer is a 7900 which is 10-color. I know that Curve Create only allows for 8 inks, however I guess I've assumed that it should at least launch without errors and would (should?) allow me to create a curve with 8 or less inks.
Are you saying that the memory addressing errors at launch of Curve Create is a result of using a 10-color printer?
