Thanks for your response DieHard. I'm aware of what you say about this version of Nuendo. I have read the posts related to that issue. However, i have about 10 Nuendo projects that were started in the early 2000's and then abandoned. My wish is to complete and finish them. I have an original copy of Nuendo 2 in my OS X machine, and it will open the N1 projects fine, but certain aspects of the mixes are not retained, like the built-in chorus settings. That's because the plug-ins in v1 and v2 have subtle differences in controls and options, and some parameters just doesn't exist anymore in N2. I want to stick to the original sound as much as i can, so i need Nuendo 1. I think Cubase VST won't open Nuendo projects, but i might be wrong. Also, the "not enough memory left" issue may not be related to Nuendo at all, right?
