# Modified Definition Base Directory Error

You have attempted to modify the base directory of a definition for which you have instances in the current design. In other words, you have instances which rely upon the current definition settings for their operation.

There are a number of solutions: you could create a new definition alongside the existing one; you could save the current design, select New from the File Menu, then modify the existing definition; or you can cut the instances out of the current design, modify the definition, then insert new instances.
