Vooner Voom

thank you! hmmm,,, it is hard for me to fix T_T

I made a mesh avatar by using blender (2.49b+python-2.6.5) and rigged with bone and it goes well in blender. but after i upload to the secondlife, it looks little strange. some vertex jump from point to point. I tried to rig again and again... but it cant go well. I cant find the cause. some person told me "edit the dae file`s vertex position with notepad++" but I dont know how to do it. please teach me how to fix.
