He's baaack . . . Andrei, When I try to use the 2 commands you show on Page 1 for calculating my improvement time, I get the following error with the 1st one (so I didn't even try the 2nd): error: 01_summary_start.xml: failed to open output file (0x800700005) I ran "take ownership" against the etl files, but that didn't help. What do I have to do to be able to run those 2 commands? Thanks again, Dick
