Error: line 595, in theme_use raise TclError(themename, "is not a valid theme.") I have messed up the themes and try to reinstall ttkbootstrap to start fresh but........

[LesHol]

I have created a function where you can choose which theme to use. I have then created a new theme in ttkcreator and saved it. How do I get it into "standard themes"? I tried to copy the parameters into the standard file but it doesn´t work.
Error: line 595, in theme_use raise TclError(themename, "is not a valid theme.")

Whatever I do, both reinstalling in my virtual environment and under Python, I still get the same error. Both the "standard" and "user" files are the default ones. Nowhere in my code or elsewhere can i find this themename referenced.

Please help
TIA Leslie
