I haven't had an issue with .dae exports, and I'm not exactly an expert at 3d stuff - the only thing I could think of would be there being a space in the file name? I feel like I remember hearing something about having no spaces in a .dae file.
When you export to collada (.DAE) you cant have any spaces in the name. So if you were naming it Scream Machine Station. It woul dbe ScreamMachineStation.dae
