OS Deployer 4 - Scheduling Failure

OS Deployer 4 - Scheduling Failure

Receiving the following error:
 
"E00090002: Failed to add the scheduled task.
 
An unknown error has occurred. Please reinstall ManageEngine OS Deployer 4 Management Console."
 
Result in Event Viewer:
 
" Scheduler failed to run task with GUID "changes every event created" because of error 2 (Failed to find the file (folder) or the key (value) in the registry.)."
 
Imaged a number of machines on the 19th March 2014 with no errors showing. No changes were made to the system over night. First log of issue with failing to schedule tasks was at 09:01:47 20th March 2014.
 
Has anyone else come across this error, and is a reinstall of the OD Deployer 4 Management Console the only solution?
