Hi LabView Q,
Are you able to acquire images in Measurement & Automation Explorer (MAX)? Or, are the images all white in that environment as well? You might find this KnowledgeBase useful. Are any errors thrown at all? Or, does LabVIEW simply crash every time you try to run this program? One other thought, you might check out this document on variables, which will help you stop your parallel loops without aborting the code. One possibility here is that your references are not being closed when the program is aborted. So, then, when run over again, this MIGHT be contributing to your unexpected behavior.
