If you're using constraints to animate your model or do anything else, I'm pretty sure they're not supported by HPL2. As the warning says, you could try to bake them into animations, but I have a feeling that won't work.

To fix the other issues, my guess is you have to "delete history" on the model before exporting.

Also, it looks like you're using IK as well. I'm not sure if HPL2 supports IK and FK or not, so you might want to try removing them if the model still doesn't export properly.
