How did you managed to run T-rex automatically on rig start, and don't know how to use a miner?
I'm asking because this is not so simple to do
Assuming you're using windows, just go to the official thread of Trex: https://bitcointalksearch.org/topic/t-rex-0268-ethw-etc-dual-mining-gpu-miner-4432704
On first post you can see the link to his Github: https://github.com/trexminer/T-Rex/releases
Go and download this file: t-rex-0.19.11-win-cuda11.1.zip
Extract and you'll se a lot of files, but you can just grab t-rex.exe and put on your old trex file
or copy the .bat file you're using and put on this new folder and execute
If you're not seeing any file, only .md, you probably have antivirus messing with your files, so disable antivirus first
