After installing Cubase 6.05, when I try to load Amplitube 3 as an insert on an audio track, I get the message “VPN plug-in rejected VPA Host” in a error dialog and it wonlt load. It loads fine as a standalone and it also loads fine as a plug-in in other apps, including Wavelab 7. It also appears to be fine in the “Plug-in Information” window (it appears there and is cheked with no errors).
Does anyone know what the issue may be?
Same prob but BEFORE the Cubase update…
I had to update Windows to get this to work again.
This help? Cubase: Music Production Software | Steinberg
only thing I could find on a quick shufti.
Could be a job for support? Might be quicker response.
Winds up the the problem was stupidity on my part. I had moved a prior version of Amplitube 3 to a folder and subsequently (and recently) installed a new version and forgot to replace the one I moved in the folder. So I had 2 versions and was trying to load the old one. I assume Cubase got confused. 
I deleted the old version and everything works fine now.
