WPM Transactions not successfully playing when monitored

A transaction was recorded on the WPM server and successfully run in the recorder.

However, when the Recording was enabled in the transaction monitor, it appears that it cannot successfully run through the recording.

I was able to pull the logs and the following keep repeating.

2015-07-13 12:32:19,526 [PlaybackDispatcher] INFO  SolarWinds.SEUM.Agent.WorkerProcessManagement.WorkerProcessLauncher - Worker process d5383197-cd06-463f-84ca-e19c8f53b1b1 has pid 5740 and runs as user SEUM-User-1

2015-07-13 12:38:59,414 [WorkerProcessMonitor] ERROR SolarWinds.SEUM.Agent.PlaybackDispatcher - Transaction of recording e8c6be45-355b-4f03-be4e-427be5e0c297 errored. Trying repeated dispatch.

Would any of you know if what would be the root cause of this?

Any information would be greatly appreciated.

Thanks
