I did, and that's why the Konica Minolta Dimage Scan Dual IV is a great scanner as it automatically winds through the APS films scanning each film. Vuescan was a life saver to be able to continue using my scanner!
I use Vuescan with my Dimage Scan Dual IV! It works a dream. Software is much better than the Konica Minolta software. Also, works in modern Windows and Mac OSes.
I've been using this for 10 years. It's a fantastic piece of software and allows me to continue to use a Konica Minolta Dimage Scan Dual IV without any issues! My APS films are still scannable! Woop woop!
If there's a potential risk that someone could gain access to your system by breaching theirs then I would raise it with them immediately.
As they're accessing your system you can probably safely say you always do a security check on hosts connecting to your system to ensure there aren't problems. In this instance it showed that they have an open FTP server.
