I got the Butel ARC PATROL earlier this year, but I am just starting to use it now. One of the things that I noticed is that the tabs on top are not lining up with the selections on the side. I suspect that I may have somehow corrupted the data. I used Sentinel to download the database, but then I used Butel ARC PATROL to configure the Favorites. Is it bad to switch back and forth between the two? Also, should I start over and just use one or the other?
