First;y, sorry if I have posted this in the wrong place. I am still new to this.
I was using Ver 8..., and then "upgraded to" to Ver 9.
Probably my fault, but I lost all the components that I had drawn. Not an issue as there were not many.
I have managed to make new directories, as before, but when I try to make a new Schematic, or PCB symbol, I get this message.
It would seem to be looking for 8.1 info rather than 9.0
As ever, your help is much appreciated.
