We just bought a 3rd Q10, and upon installation, suddenly began to have the following problem: When the Aardvark Manager is opened, it works fine *until* we view the mixer for the 3rd card. Then, within minutes of having that screen visible, the program crashes, and also prevents us from reopening the program, or any other audio programs, until the PC is rebooted. And for those of you wondering, we are well versed in the ways of troubleshooting, and we have taken the time to swap out all of the cards across different PCI slots (we have 5 slots, and have tried every combination) and have used different cards with different cables and input boxes. We've uninstalled the drivers, and reinstalled every version of the drivers we have, to no avail. Pull out the third card, and the system works fine. And if the third card is in, as long as you don't view the mixer interface for *that* card, you can keep the interface for either of the other two cards open, and the app will not fail - until you try to refer to that third card in any of the settings (for example, the ASIO settings for the master card; if you set it to the 3rd card, crash). Please, if anyone has experience using a third Aardvark Q10 in a system, respond and help us figure this problem out.
