Config File not working

[fatheaddrummer]

Hi there and thanks for this awesome tool!!

Undortunately I can't get the config file working:
I tried several options in the last 2 hours but none of them did the trick

This is my command (one of many different trials):
mrswatson64 -p "Virtual Mix Rack" --plugin-root "C:\Program Files\VstPlugIns\Slate Digital" -i v-test-1.wav -o v-test-out.wav --config-file options.txt

And this is the error:
INTERNAL ERROR: Set ProgramOption with invalid type This should not have happened. Please take a minute to report a bug. Support website: https://github.com/teragonaudio/mrswatson/issues Support email: support@teragonaudio.com ERROR: Cannot read options from empty filename

I am working with the latest Release on Windows / 64Bit...

Any advice will be highly appreciated! Thanks in advance!
