Mr. Eads,
The serial numbers that I emailed you in my first email came from my text file and not from the computer stations.  I have not looked at the “Help” screen for the serial numbers on the actual machines.  After purchasing the (4) four software packages, I made a text file to store these numbers in case one or more of the software package(s) went missing.  When I emailed you those serial numbers I believed this text file to contain accurate information for all four serial numbers of the software packages that we purchased; this was to be my fail safe method to retain serial numbers.  Apparently, the third number is either incomplete or it has been altered and the 4th number does not appear to be an accurate serial number at all seeing that there are just repetitive numbers.
I am still searching for those (2) two other AutoCad 2010 software packages.
