Thanks for your help guys - right now I'm baffled.
1. I was able to remove all XLN references to my old pc id.
2. I registered with the new ID.
3. I can run X3. I'm not saying I can't. Its just that with XLN loaded, after about 3 seconds of play, I'll
get a dropout, and then when I reset I get "unable to open audio device." and then sometimes I get a message
about not recognizing the audio format of the project.
4. IT doesn't do this all the time. Sometimes I can play the project for a bit and no error. Other times I try it
again, and it abends in 2 seconds. No pattern or predictability.
I checked all the Device settings in Preferences - exactly the same as in Windows 7. The Firewire chipset is fine, and compatible. No reported issues. FOcusrite plays great outside of X3, and all settings in device manager are correct.
I am SO baffled. I tell you, if Windows 10 is making my mobo perform bad, then I'm sunk. Admittedly its an Intel Core 2 Duo E6700. Its just that it works GREAT with Win 7!
Am I hosed?
