You will get an error when saving a profile file (it will also occur when the auto-save function attempts to save the file) when both these points are true:

  1. a pole ID has a space in it
  2. you have saved the tipload for that pole (through the Pole>details>open pole in tipload>save to profile function)


rename the pole ID removing the space.

This is a known error in the current build of version 7 and will be fixed in the next update.
