exec (MEL)
"The string argument is a command which gets executed as a background
process from the shell"
That would be launching your python script in its own process, outside of
Maya, and most likely failing but you aren't checking the return code to
know.
I think what you really want is the python "execfile"
"Read and execute a Python script from a file.
The globals and locals are dictionaries, defaulting to the current
globals and locals. If only globals is given, locals defaults to it."
Also, just use forward slashes all the time, even on Windows
Does this work the way you expect?
python("execfile('/Server/MyFolder/Save/LPLFile.py')")
