'Insufficient memory' message

SimonACT Birmingham UK
I'm getting an 'insufficient memory' message come up when trying to load a particular paint recipe for our robot through RobTalk.  I can't edit the file (thought about copying then renaming it in case the file is corrupt), as I just get the memory message with no option to do anything else.  

The robot is a TR5002 and the control panel is a C5.3A

Any ideas as to what I can do, or is it a case of just having to write out the program again?
