Issues with importing animated dae (Collada) files

I have been trying to import different types of animated .dae files into unity 2.6, but have been unsuccessful. Keep getting UnityFBX import errors(unidentified error). There is no problem imported just the collada model.

These .dae were exported from maya, I also tried some sample from collada.org

I want to avoid reconverting all my assets into .fbx from .dae. Is this a bug on Unity side or the FBX importer? Is it possible this is resolved in Unity 3.0 release?

I had a couple bug reports on "unidentified error" with dae files and they have been fixed in Unity 3.0 (the problem was on FBX SDK side). I believed Autodesk improved support for dae files in FBX SDK 2011.2 release (the one that is used by Unity 3.0).

You can also submit a bug with your files attached (and send me the case number) and I'll see if Unity 3.0 can import your files.
