In case you have a Windows user account with special characters in it:
There currently is a glitch where sometimes vorpX can’t properly access the profile database if a Windows username is used that contains special (non-ASCII) characters. This will be fixed shortly with the next vorpX version.
Until then please try the following workaround:
1. Create a second Windows user account with only ASCII characters in it (e.g. “arduano”).
2. Reinstall and use vorpX with this new user account
