Hello,
we appreciate your contact.
The wrong datatree error indicates that the installer which you've used is older than you config file and it can't "read" the config file. You should download the latest version of PRTG or the same version which was previously running, that should resolve the issue.
Please be aware that PRTG version 12.xx dates back to 2012 and is no longer officially supported.
Please feel free to Contact us and you will be able to forward us your log files so that me way send you an up-to-date commercial installer.
Best Regards,
