"Cannot have more than one outer loop" in ECAD-MCAD Collaboration for IDX

I am using Creo Parametric Release 9.0 and Datecode9.0.8.0

When I am transition my old IDF board to an IDX file, it is giving me an error with my ECAD areas. When I try to edit the sketch of my ECAD area and hit "OK", it gives me the error "Cannot have more than one outer loop". I have several circular areas within my sketch that all should be route keep outs.

Is it telling me that I have to make individual features for each of my many zones?
That would be a very inconvenient way to model several of the same type of zone. Each zone is slightly different and can't be created using patterns. Is there a workaround to this?

Here are the errors that I faced
"Cannot have more than one outer loop"

Starting with Creo 12.4.0.0 the functionality you are seeking became available. See release notes here: https://support.ptc.com/help/creo/creo_pma/r12/usascii/index.html#page/whats_new_pma/ecad_sketch_regions_support_for_ecad_areas.html 

 

In Creo 9 you are probably stuck with using a separate sketch for each ECAD area definition (one closed loop per sketch). It is likely possible to pattern or generate sketches for the circles; post the sketch of the circles you want to use to define the keep outs (just save the section from within sketcher). You must zip the sketch before posting.
