As a note, when you log in to the ETC 1.1, your old workbooks will be marked « Out of Date »:

  • When you load them, they will open in Read-Only mode: this ensures that your version 1.0 results are not overwritten and remain available to you for reference.
  • If you copy an out of date workbook, and load the copy, all its calculations will be automatically updated for you with the current version of the software.
