If you are a little bit higher at scripting, here is better way:
Open
mpl_RS5k_manager_data.lua,find Data_Update() function, paste
before the function ends to make sure it is not breaked by some condition. Save mpl_RS5k_manager_data.lua with Cmd+S and then close RS5k manager and run main script again (changes in child scripts only appeared on main script initialization).
If it`s okay, next test is to do same thing in GetRS5kData() function to check if this ever try to take data from RS5k instances.
