Thank you very much. This worked!
However...
The reason why I decided to do a clean install of GIMP and GMIC was that when I tried to refresh the GMIC filters, I got the following error - and I still get the same error, so a reinstall didn't resolve it :-(
"Filters update from Internet(partially) failed! Unable to reach these filter sources:
gmic.eu/update1610.exe"
(it actually says
https://etc but as a newbee apparently I'm not allowed to post URLs)
Any suggestions?
-- updated:
I copy/pasted the URL In the address bar of my browser ad it says "Not Found - The requested URL /update1610.gmic was not found on this server"
Is there any way to change the URL the "refresh" tries to connect with? And what should it be changed into?
Thanks!
