Scheduled tests no longer running / no log files to reference

Hey, 

I'm having a similar issue to this, our tests were running regularly and reliably, then for no apparent reason they stopped, i cant find any errors and logging on reads:

[06/20 07:32:09,Telerik.TestStudio.ExecutionManagerService.exe(1308:20),Execution] JobRunner.RunJobAsync() : TestList loaded for job ID = 5d25d4f6-3e9f-4c37-8dab-96317d899ae3
[06/20 07:32:09,Telerik.TestStudio.ExecutionManagerService.exe(1308:20),Execution] JobRunner.RunJobAsync() : Job started, ID = 5d25d4f6-3e9f-4c37-8dab-96317d89

Then the job vanishes from the results page, and there is no trace of it. I dont want to have to create a new test database. is there anything else i can do to resolve this? 

Thanks
