I am new at moho (and in english), I tried to export the landscape.moho file (the sample file comes with moho) as swf. But when I trying to open the exported swf, my flash player always crushing.
Is there any way to prevent this situation? (I need a help about moho files that contain full of camera moves and bones and other things that flash doesn't support)
SWF has some restrictions and can't display everything Moho produces. See in the Help file (Moho User's Manual) Reference -> Flash tips. However, you can export to a movie format and import that into Flash MX (I believe FLV is the preferred format for online viewing bitmap material in SWF).
First you must export your animation as a mov or avi. Then convert to flv, and the Lost Marble recommended Riva FLV converter (google for it) works for me.
Moho can't export FLV directly, but you can convert either an AVI or QuickTime movie to FLV. The Flash authoring tools have an FLV encoder, or you can get third-party ones like this free one:
