Mesh objects don't show up, despite being in the model folder

[Christine Dailey]

I download the FESCycle model and copied the objects into the same folder. I also copied them into my geometry file. My preferences are set to locate the file. The model uploads successfully. However, when I scale the model I get an error:
Error loading mesh file: pedal.obj. The file should exist in same file with model

I triple-checked this. They are all in the same folder. And the name is the same name used in the model .osim code
Any ideas?
