just passing through and noticed this post and I thought I might throw my two cents in:
Have you tried importing it as an eps file? I'm not familiar with the plug in you used; but you can try the ESPF loader plugin. It has settings where you can adjust the number of points that will come in with along with some other settings that come in handy. I just checked and in 9.6 the plugin is version 2.1 By using the curve division level you can control how many points are include and it does a pretty good job for the problem you might be having, can't remember if you have to save the file in illustrator in an older file format, been awhile since I used it, I think it has to be in version 9 format or earlier
