Hi the link http://bbs.blackview.hk/viewtopic.php?f=192&t=436084 does not appear to work.  Is there a new link
Will this update fix the camera issues or do I need to install a previous version first
Thanks

What problem with your camera?

Can someone please post a new download link for the checksum generator? The old one doesn't work anymore. Thanks in advance.
