Sure,
The key shows up eLC. Periodically, and non-reproducabely, the licenses will all vanish, it will pause for a momment, and then refresh them. I've tried using different USB ports for my key and it has no effect on the problem.
Ocassionally, after working fine for days/weeks/hours, vienna will refuse to load. In Logic, the AU will simply crash. In standalone, it will freeze for a few momments and then pop up a dialog box that you can't get rid of saying either "connect a valid eLicense" or "Woodwinds II (Or whatever other library) caused a crash".
Ocassionally Vienna (Standalone or AU) will simply not start with no explanation.
I have a ritual that "fixes" it but I'm not sure what steps are important or not. I repair disk permissions, restart the computer and clear my PRAM (found this arcane tip on an Apple support board). Occasionally this works. Occasionally you have to keep restarting over and over again and eventually Vienna will "magically" start working again with no explanation.
I'm running a Mac Pro workstation with a another securtiy dongle for my other apps and an M-Audio fast track pro USB. 2X2.66 Ghz Dual-Core Xeon, 4GB Ram 667 MHz DDR2 FB_Dimm; Yamaha keyboard and Oxygen II MIDI controllers on USB as well.
I'm complaining about the permissions issues here, rather than to Apple, because my other security software & dongle combo (for EWQL, Symphobia, Stylus etc...) never causes problems in the same way, never crashes, never delays or derails my poroductivity and generally doesn't require any sort of bizzare or arcane computer ritual to fix. No PRAM zaps, no permission resets. Vienna chose to roll with the non-industry-standard security platform, and this is causing your user base a great deal of difficulty for no benefit.
Again, I love your sample libraries but have taken to not using them when I'm under deadline pressure because I can't take the risk that they will spontaneously stop working. (This happens a lot, say 5-6 times a month)
