Flash 8 (the current version) has a security feature that precludes importing files altogether. If you already have Flash 8 installed, go to the link below and use the un-install tool, then install Flash 7.
To determine which version of Flash Player you have installed, put your cursor over the Work Area in Icovia, and right-click your mouse. The Flash Player version will be listed as "About Macromedia Flash Player n" (where "n" is the version.)
