Problem resolved.

I generated a new Configuration file, with the three Profiles, and loaded it on to a properly formatted USB flash drive. Inserted flash drive in Car 2's ALP USB port, and load was successful. (Car 2 is the one I had problems with a few days ago). I then took the flash drive and inserted it into Car 1's ALP USB port, and load was successful (I changed a couple of selections from what was already in the system). I then downloaded a Statistics file from each system on to two different and properly formatted USB flash drives, printed hard copies, and compared them with each other. I also compared them with a hard copy printout of the Configuration file with the three Profile's selections. All selections on the three Profiles in the Configuration file matched the Statistics print outs.

I do not know what caused the original problem, but I now know that I can load a Configuration file with the three Profiles on to a flash drive and successfully load the file on to both ALP systems.

Thank you to everyone who posted advice and suggestions. I appreciate your help.
