Kaltura CS - Quitting before saving

Sorry if this issue has been addressed but I cannot find a solution anywhere. On a few occasions I’ve quit KalturaCS before stopping the recording. The file is in tact but unable to be opened. Likely the file needs to be repaired. Is there a solution to repairing the file? Shouldn’t;t there be a safeguard to prevent quitting in the middle of a recording. Thanks for any help someone may provide
