Fusion 8 not working with Deadline 8

We have recently updated to Fusion 8 and we're having issues getting it working with Deadline 8.
The job starts on the render machine but immediately fails with the following error in the log...
2016-09-15 11:41:44: 0: Done executing plugin command of type 'Start Job'
2016-09-15 11:41:46: Scheduler Thread - Render Thread 0 threw a major error:

We've updated to Fusion 8.2 but this hasn't fixed the issue.
