LaserSoft Imaging

I downloaded the demo version of Silverfast a couple of hours ago and installed it - just to make sure it would go together with my Minolta Dimage Scan Dual IV. As it did I immediatly bought the SilverFast SEPlus version just to get the AACO function (even if I noticed I got the low budget version with four presets.) and entered the serial number as told. When checking the serial number shows up.
The software functions well - except I can't get the AACO corrections to stay. When I click on the AACO button the dialogue box opens, the use AACO checkbox is checked, I chose one of the presets and the changes take place on the photo.
But when I click "OK" to leave the dialogue box the AACO adjustments disappear. :(

It sounds like you are saying that you no longer see the changes in the preview and that is the normal behavior described in the user manual. You will see the changes while in the AACO dialog and in the final scan, but not the preview.

Hope this helps!
