A couple tips.
Regarding the frame alignment issues. If you are on a PC make sure you download the latest drivers from the Plustek website. Mac or PC users: restart SilverFast, go into the Service Dialog and select Reset Software. That should take care of the alignement issues. There will be a new driver release for Mac in the next week or so. Watch our Facebook page, Twitter or the Download page on Plustek.com
A note about downloading and installing a new Plustek drive release. After downloading and unzipping start it by double clicking "install.exe".
The first time you do this the programm will UN-install the old driver and you have to restart the PC (i'm working on W7 32).
Next start install.exe again and now the new driver is installed. Again you have to restart the PC.
I also did the Reset Software in the Silverfast service menu which is on the splash-screen.
No doubt that Silverfast has issues concerning the way it finds frames to scan. When i didn't select a specific film size (guess the default Transpary Size setting is 35mm) and used the Workflow Pilot, Silverfast showed me a preview of the whole carrier area. That by itself is not an issue as you could reposition the red frame and zoom in. Worse was the fact that the images (3 images 6x6 in my case) were not centered in the preview window but to the right border and even missing part of the image on the right side. Silverfast should correct this issue.
I was succesful in finding and scanning my 6x6 images by not using the Workflow Pilot. First choose the right Transpary size, then the right Filmmaterial (in my case Negative). Next let the scanner search the images by using the "Overview" button. In my case this button was hidden and has to be reached by clicking on the arrow on the bottom of the Vertical Tools bar.
After the software has found the frames just select the one you want to scan and clcik Ok. Now the scanner will transport that frame to the scan area and give you a preview of that.
Earlier yesterday evening had a problem whereby Silverfast crashed everytime i hit the Scan button. Also after re-powering the scanner and restarting Silverfast. This problem could only be solved by a "Reset Software" in the service menu (Splashscreen).
Guess that both Plustek and Silverfast have still some work to do in order to produce a dependable setup.
