The Vienna perf. tool has up to three legato modes for its different products. With the saxophones, you need to select the "HOR-LEGATO" mode in the pop-up below each channel name. I'd be willing to bet you'd simply selected "LEGATO" which is only used for their 1st and Pro Editions. That is how I can make the "File Type Does Not Match" appear. If that's not the case I'd definitely email VSL because something else might be wrong.
