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:

XP/2003: C:\Documents and Settings\All Users\Application Data\Paessler\PRTG Network Monitor\V7\
Vista/2008/Windows 7: C:\ProgramData\Paessler\PRTG Network Monitor\V7\

Please be aware that it might also be a 'V8'-folder.

Best Regards.
