Cinema 4d files - animations in separate files

Hello, I've have a bunch of cinema 4d files which contain animations like running and walking, and one which has the character in a T-pose, all the same rig.

Unfortunately I don't know how to work with Cinema 4d, but I need the animations for unity.

I've Imported them in unity, and sure enough the animations work (I can preview them just fine with the files own rig). However the problem occurs when I drop the T-posed character in the preview, the animation plays but its deformed presumably because the animation file doesn't have a t-pose just the animation, I can edit the avatar of the animation and see that the enforced t-pose is all weird looking.

I'e tried many combinations, with Generic - it doesn't work at all, with other avatars copied.. I cannot get the animation to be as its supposed to. I'm not sure how to use the animations when they don't work with the t-posed character.

I've also wanted to import the animations into blender and then copy them onto the t-posed character, but the imported animations (collada 1.4 / 1.5) are deformed off the bat (on the rig that imported with them), so I have no idea how to fix this.

Any idea of any possible way to remedy this? Not necessarily within unity. I'm working with unity 5.1.1, Cinema 4d r14.042 and Blender 2.71
