Problem with custom line styl between Microstaion v8i Select Series 3 and Microstaion v8i Select Series 4

We have a DGN file that we want displayed with custom colors and linestyles in Microstation. When we open the file in Microstation v8i Select Series 3, and specify the custom .rsc file containing the custom line symbols, the lines draw with the correct colors and line symbols. When the same process is following in Microstation v8i Select Series 4, the lines are drawn with random, default symbols instead of the correct symbols. We would like to know if anyone else has run into the same issue.
