Confusing error message from iTunes when trying to use AirTunes

Question

Hello everyone,
I figured since other folks might run into this issue that it's worth posting about, since it's both annoying, irritating, and none of the Apple support hints address it properly ...
If you're one of those folk like me who has to deal with corporate proxies for pretty much everything while at work, but don't have any local proxy issues at home, you might use something called Proxifier.
Be aware that the way it works (as a kernel module, intercepting socket calls and transparently mapping them through your defined proxy) will screw up iTunes unless you explicitly unproxy it (it implicitly proxies everything except what you tell it to).
The error message I kept getting was "The remote speaker is not compatible with your version of iTunes", and after spending 20 minutes or so with ktrace, watching socket calls, I gave Proxifier a poke and told it to stop proxying iTunes. Lo, and behold, AirTunes magic returned.
So if you use both of these applications, be wary of the interaction between the two, as it can be confusing and produce undescriptive and unhelpful error messages!
cheers,
Klaus

Hi Mars-
It sounds like your NI-DAQ installation may have become corrupted. I would suggest uninstalling and reinstalling the DAQmx 7.4 driver to correct this problem and ensure that you're up to date. This download is available here: NI-DAQ 7.4
If the problem persists you may want to uninstall and reinstall LabVIEW and then NI-DAQ in that order. The error message will usually give an indication as to which VI the error occurred in. Please let us know which VI is failing if you're unable to avoid the error with these suggestions.
Have a good day-
