Did you run the script to fetch the proving keys? If you build from source, it’ll be ./src/zcutil/fetch-params.sh and if you installed from binaries just run zcash-fetch-params
Thank you for getting back. I actually found an old forum post about trying with a fresh terminal and that did the trick strangely enough. Good to go now, thank you for taking the time to answer my question :).
No problem! I’m a volunteer here, but even though I’m not an employee of ZcashCo I do make my living with all kinds of things Zcash related, and helping out beginners is essential to any open source community
