curtain model

[DRedshot]

I've been trying to solve this problem i have for a couple of hours now, and have finally decided to ask for help.
For some reason, when I export the mesh (as OpenCollada) it is all messed up. It's not a general export error, it's something to do with the joints, I know this because the right side of the curtain looks fine, and i haven't binded that side yet. However the left side is very distorted, and looks a lot different to the version in maya...

I'll update the first post with a pic, so you can se the problem.

ps: the mesh in ModelView is static, it has no physics, so the error isn't the joints 'stretching' apart...
