Statistics not working

[elenlace]

Hi,

Statistics (webalizer) have stopped working a few days ago, when I try to run them manually I get this error:


C:\Documents and Settings\Administrator>"%plesk_bin%\statistics.exe"
Error: Unable to restore run data (10)
Error: Unable to restore run data (13)
Error: Unable to restore run data (13)
Cluster Notification Provider not loaded

Any ideas?
