Error when importing dae file

Hi,

i have a (large, 32 MB) dae file. I could import this file in the past, but now when i need to import the file again, it throws an error:

ImportFBX Errors:
Couldn`t read C:/Desktop/file.dae.

I tried to open this file in Blender and Meshlab and it could be imported there. So i tried to export it from Blender and Meshlab again, but the error is still there.

Any idea why it is how it is or how to fix it? Im out of ideas, it worked half year ago but now.

ps: when i export the dae file in Meshlab/Blender as an .obj file, i can import it into Unity. And if i export it now from obj to dae it doeasn’t work. I need it as dae :confused:

@Dimerk,
I have run into this quite often, and just seemed to fix it by breaking my one large mesh into several smaller meshes all in the same file.
