You will need to post more information about where the error is occurring in your project, which will require you to do some extensive troubleshooting and giving a good explanation of the scope of the occurrence.
If you want you can create a support request with National Instruments, but again you will need to do that initial troubleshooting and we would like you to include your project so we can see if we can reproduce the behavior. Go to www.ni.com/ask to submit a support request.
