Hi there! You’re out of luck unfortunatley, though all is not lost…
Hasselblad has basically given up on their scanners which I’m guessing is why you’re not getting a response regarding this issue. Flexcolor only works with x32-bit operating systems and is no longer supported on Catalina and other x64-bit only operating systems.
So, if you’ve upgraded to Catalina, your issue might be there - if so, you can either downgrade to Mac OS Mojave or earlier, or get an older Mac computer running an older operating system to use specifically with your X1
If you’re using a computer running mac OS Mojave or earlier (or a PC with 32bit support) and it’s reading the scanner, but crashing while scanning, unfortunately, you might need a new scanner motherboard. I sometimes rent scan time on an X5 in London and they had a similar issue. Luckily they got it fixed by replacing the motherboard but it’s not cheap - upwards of £600 if I remember correct, plus labour fee
I see you’re in South Korea - if you don’t have a repair contact already, your best bet would be calling rental houses that have Hasselblad scanners for rent in South Korea, telling them you’re got a problem with your scanner and see if they know anyone who could fix it for you. If they know someone I’m sure they’ll be happy to recommend them to you
I’m genuinely sorry to hear you’re going through this - it sucks especially after spending so much money on a scanner that is no longer supported by modern OS’s and is soon to be un-repairable after parts run out.
