Wavelab Element 7 - can't insert files in "Montage Workspace

I created some wav files with Sequel 3, and I can open them in Wavelab, in the “Audio Workspace”, but if I try to open them in “Montage Workspace”, I get this message : “wavelab the following file (s) were not inserted (check the number of channels and the sample rate)”.

Has anyone else had to deal with this issue? If yes, were you able to resolve it?


Hello, is the track in Montage mono/stereo, matching the one from Sequel (you can create mono or stereo tracks, and mono/stereo must correspond to mono/stereo files imported)? when creating a new montage, you must specify the sample rate. Is this the same as in Sequel?
Hope I helped
