I purchased my #3 SDS100. Other two running fine, sentinel fine. #3 arrives, quick connect, fav lists, all good. So I realize I have a "better/newer" laptop, download sentinel, on it, connect #3 to it, "write from scanner". NOTHING. So I reformat sd card, and erase user settings, and run from zipcode. ALL GOOD. So the sentinel software is not working anymore. The orig sentinel/laptop is gone. To reiterate- sds100 will not run from my fav lists on sentinel. The scanner LOOKS like it will, shows systems, depts etc. Nothing received ever. I tried to uninstall sentinel. How can it reinstall with my fav lists already listed? Something not right in the programming. Please help!
