Can not start cross studio - wrong path to installed packages

Hi.

I also submitted a request for help 22 hours ago but no reply yet, so I am asking the user forum now.

I accidentally changed the path to the installed packaged in the options menu. I then exited CrossStudio, and now it will not start again.
I tried uninstalling and installing again, but the same error occur. Looks like the program is still searching in the wrong path for the packages and this path is not reset when uninstalling. Maybe a windows registry that is not deleted when un-installing?

If anyone have any ideas please let me know as this is very urgent.
See attached picture for error.
Best regards,
Jacob
