it seems possible to download the last version but I think is not mine because this note:
Important: The installers available here correspond to the download version of HALion Symphonic Orchestra currently offered in our online shop. The original HALion Symphony Orchestra - distributed on multiple DVDs in a box only - is a separate product with a different range of features.
Any ideas about the possibility to recover my version?
Thanks
