IT doesnt surprise me with Nvidia or Creative, both have this error alot with pro-audio aps... but the Mbox should have pretty decent ASIO drivers, do you have it set to be your default sound device in control panel prior to opening VE?
Yes. I have set die Digidesign-ASIO and the very well working Creamware Scope-ASIO as default audio device, but always the error occur.
Using VE as VST-Plugin I can't not set any sound-device, becauses it uses the sound device of the host software, and the error occur too.
So I don't think the error is specific audio driver dependent.
If it would be a problem with audio drivers, then it should be occur in some other applications, like the VI, Sonar, Reaper, Kontakt2, ProTools etc. too. But all this applications do work fine.
I mostly do work in ProTools and maybe VE could help me alot, because of no current RTAS versions of VI. So it would be nice to bring VE on the run on my machine. [:)]
