Newbie- SCM Record 2 problem with file transfer

[branchy]

Hi,
I have worked on a multicam for a couple of years and decide to purchase a second hand SCM Record 2. There have been a lot of teething problems and I thought after a month I had everything covered.Not so... I am going through a post processor being DNC precision which is compatible with NUM 750. I can transfer the file no problem at all, however I am not having any luck initiating a program. I created a simple line and planned to do a dry run but had no success in anything happening at all. The following is my Gcode file.I am new to gcode as Multicam bypasses that lingo. If anyone can tell me what I maybe doing wrong I would be most appreciative. By the way the last line is the suggested block that DNC Precision use for conversing with NUM 750 to end the program
Cheers
Chris.
