I think you're supposed to only provide the file path without the "FILE default".
Have you tried using the absolute path? If your stellar-core.cfg is in /somewhere/stellar-core.cfg try using the full path.
Just using the file name will force stellar-core to look in the directory where it was installed to and your file probably is not located there.
