Adobe bought Macromedia and killed off fireworks. I still run the last version they made.
I know your pain.
Once you learn how to do everything in an editor and they stop supporting it you need to either reinvest time into learning a new editor or in supporting the obsolete one.
I’ve chosen the latter for now mostly because there doesn’t seem to be a clear winner in the market and I hate to keep investing time in learning new workflows every couple of years to do the same task when I can just keep a VM operating to support an obsolete editor.
