Hi, I'm new to this forum. I don't know if anyone else has encountered the problem I did today, but beware of an issue if you install Lion on your MAC and try getting SilverFast scanning software to work. I purchased SF Ai Studio on April 15th. for $312.00. It won't work on Lion and Lasersoft now say if you purchased it before June 2011, you won't get any financial consideration for a replacement. When the new Lion compatible version comes available at the end of August, a purchase of that new version at the FULL price will be necessary. 3 months use and it's useless. Stinks of a corporate rip-off to me. So it's over to Vue Scan from now on, LaserSoft are not getting another cent of my money!
