Hello,
there seems to be a problem with the configuration file (it may got corrupted).
Please try to exchange your running config file
PRTG Datafolder\PRTG Configuration.dat
for one from the auto backup folder
PRTG Datafolder\Configuration Auto-Backups
yesterdays config or the one before and then start the PRTG services.
You will find the the data directory as defined under the "Core Server" tab of the "PRTG Server Administrator" tool, or in the following default paths:
Please be aware that it might also be a 'V8'-folder.
Best Regards.
