@bgugs:
…
What exact error message do you get? Oddly enough the file just opened after trying it… of course after 50 times of trying it won’t work until I ask for help. I will see if this remains successful or if the message comes back
I experience Inkscape to take a very long time to start most of the time.
So on my PC it is always a good idea to first start the program - and to load the file after Inkscape has successfully started.
Good luck! :-)
