[AMSAT-BB] ISS on Satpc-32

Greetings all-I realize the ISS can change orbit slightly. When I use the amateur.txt file to track it it's in one position, when I use nasa.all file it's somewhere else. I thought when I clicked "up-date keps everything was updated. When selecting the source files provided in satpc32 I get a lot of "download failed". Help with confusion please. Thanks 73 Bob W7LRD
