Epsom DS-50000 scanner with new drivers for use with Big Sur

Hi guys.

I was wondering if anyone has dealt with running an Epsom scanner with the new drivers after upgrading to Big Sur.

I've got two issues.

I got the new drivers installed, but the scans, which used to be fantastic, are now coming out with huge amounts of contrast and way over-saturated. I'm gradually pulling it back by juggling the scan settings and photoshop, but frankly, the results just aren't as good - they look, well, cheap. Has anyone had the same and found a fix?

Secondly, until I installed the new Epsom drivers, Big Sur was working fine - spent the day painting with a large file, full of layers and really pushed the system with no issues. But since adding the new drivers, I'm finding all sorts of apps are hanging when I open them - even finder. I've had to use the dreaded Cmd+alt+esc several times, and even then once even that didn't work. Clearly the drivers are causing issues, and again, I was wondering if anyone has found a solution, which doesn't involve hurling rocks at the screen and shouting lots.

Should I just give up and install a previous OS? Or would that just cause more problems?

Sorry for the involved question!

Luke.
