Unfortunately Scancrap has a very poor reputation with its software development insofar as their Lite Plus product is concerned. There have been MANY reports of folks' scanners getting seriously messed up when using it; and as I understand it, RS stores are moving away from using it (they used to use it to pre-program scanners for people when they bought them - only to very often screw them up too).
I did a review on this software years ago when it had just come out - I believe (this is simply my opinion) that the software is being 'pushed' without proper research and testing. You cannot expect to be able to support every scanner that this software supposedly does without at least testing it on an actual unit. In most cases, I doubt that this is being done. I suggested to the author that he form a beta group with users of each scanner in order to fully test it before release, and you can guess where that suggestion ended up.
To be fair, at least some of the issues come from users who simply don't understand what they are doing. But well-designed software should account for this, at least as much as is possible. The code for the grids and design was developed by a third party, for which the author had to pay a licensing fee, with evidently little knowledge of how it worked, at least in the beginning. I suspect he dug into it for later versions, but that only hurts the development and testing cycle even more. I know from experience how that cycle can end badly.
Another shortcoming was being married to what is nothing more than a fancy FCC data dump, instead of using RR for its data source. In point of fact, they did have a version (briefly) that had a copy/paste ability to grab data from RR, but it's no longer mentioned on their website.
In short, it could have been far more than it is. It had the potential - it was wasted in the rush.
