Hi all,
Steinberg Austria did some tests for us and confirmed that they didn´t encounter any problems when loading Vienna Instruments in Cubase 4 either.
Make sure that you have OS 10.4.8 installed and please get the latest update from the Steinberg Server (Cubase 4.0.1.2074), moreover it might help to check out the following:
1) Is VST2 plug in manager active? (picture1)

2) Is ViennaInstruments.vst visible in the plug in list? (picture2)

3) If not visible, please reassign the VST 2.x Plug In Path. (picture3)

Best regards,
M a y a
