Error when integrating it into a swf in Flash Pro

[yuanyi]

I am a AS3 beginner and AS3SVGRenderer runs successfully when I test it separately (see below).

package {
import flash.display.Sprite;
import com.lorentz.SVG.display.SVGDocument;
import com.lorentz.processing.ProcessExecutor;
public class trySVG extends Sprite{
public function trySVG() {
ProcessExecutor.instance.initialize(stage);
var svg:SVGDocument = new SVGDocument();
svg.load("actors/200x160pxtry.svg");
addChild(svg);
}
}
}
I come across a problem when integrating this package into my swf in Flash Professional CS5. The codes are the same and the error report says that it can't find specific types (see below).

D:\WEBSITE\work\try04\com\lorentz\SVG\parser\SVGParserCommon.as，19 行 1046: 找不到类型，或者它不是编译时常数: SVGPathCommand。
D:\WEBSITE\work\try04\com\lorentz\SVG\parser\SVGParserCommon.as，87 行 1046: 找不到类型，或者它不是编译时常数: String。

I believe the report is wrong and doesn't locate the real mistake. Is there a chance of possible conflict between AS3SVGRenderer and other library since my swf is constructed under a pureMVC framework. How could I find the mistake, any help? : (
