Hamid, Perhaps there is a bug is SMS which is causing this crash. Will you send us your files so we may duplicate it? If the size is less than 25MB you may email them to support@aquaveo.com. If they are larger, you will need to upload them to our ftp site. I will provide instruction on how to do this, if necessary. Thank you for the questions. Regards, Josh Schultze XMS Technical Support (801) 691-5530 support@aquaveo.com
