导入的lumion sp2 b5版的模型几天后不见了

导入的Lumion sp2 b5版的模型几天后不见了，场景里只剩下lumion 的树，是什么原因？哪位大师帮助解决？谢谢

this error because you dont delete folder Lumion free in my Documents (win XP) , you must copy 2 folder Library and Scenes in folder Lumion free and paste to foder lumion . Afterthat delete foder lumion free ( in my document with winXP)

su导出模型的dae文件必须在之前你做的那个路径下 不仅仅是sence里那两个文件的同路径转移了
