one of the errors suggests maybe you had some things picked for logging before you connected to the car and that value isn't available on the car you're trying to log:

Code:
19:06:56,519 INFO  [AWT-EventQueue-0] - Loading profile: C:\Users\mateu/.RomRaider/profile_backup.xml
19:06:56,519 ERROR [AWT-EventQueue-0] - Error occurred
com.romraider.logger.ecu.exception.ConfigurationException: Unknown default units, {0}, specified for [E11] Oil Temperature


then towards the end of the log it looks like your serial port got disconnected:
Code:
19:42:46,976 INFO  [Query Manager] - Trying serial connection...
19:42:46,976 ERROR [Query Manager] - Error sending init: Parameter portName must not be null or empty


If its ones of those cheap cables with the CH340 chipset I've found them to be super unreliable.

Try closing romraider then remove your settings.xml file (in the user profile .romraider folder) - then open romraider editor to setup your config and then open the logger to configure that. Make sure the com port doesn't change and then try connecting to the car again. If no good then clear out your log file and try it again so the log only has 1 attempt in it to look through.

Good luck and may the logs be ever in your favour!
