Cannot update Corridor Modeling alg file once it is created

Using: Geopak Version is 8.11.07.227 (Select Series 1)
             Microstation version is 8.11.07.10 (Select Series 1)
             Windows XP

 When I open the Corridor Modeling tool, I can first import my geometry (chains and profiles) but when I go to import the plan graphics nothing happens...they wont show up in the ALG Viewer window.

Likewise, if I start a new file, and first import my plan graphics (from the same dgn file) I then cannot import my chains and profiles.

If I import my geometry, change my profile, I cannot re-import the profile for it to re-read the updated information. It seems like it will create the alg file for the first import operation, however, no subsequent operations will get imported or updated.

 Any suggestions?
