I'm having the same problem. I too bought the Jupiter 8v at Guitar Center. I installed the software from the CD, except Syncrosoft since I already had it installed from the Korg Legacy Collection. I believe I have the latest Syncrosoft program installed. I also have the dongle connected to my computer. When I try to open the J8v I get the following error.
When I open syncrosoft center, I see this:
I don't see Jupiter there activated. I thought I was supposed to download an activation code for the dongle to get activated like I did with the Korg Collection.
Even though I already have Syncrosoft installed, I tried to install it again from the Arturia CD hoping the activation code would come from there, but it tells me it can't install (syncrosoft) because my OS is too old and that I need 10.3 or newer. I actually have 10.6. I've also reinstalled the J8v one more time without any success to get it to work.
I thought maybe the dongle needed drivers like it says in the error message above, but I couldn't find any of that stuff on the downloads section. I did install the 1.1.1 update however, but I still get the same error message.
Does anybody know if it's compatible with Snow Leopard?
I've submitted a request for technical support, but I'm still waiting for a response. I'm very eager to start playing with this bad boy and this is just torture.
Help!!!
