Hello,
So just LCC won't open ? or both LCC and VI won't open? Have you had LLC open at all to put your licenses on the dongle?
I'm assuming you're using 10.5.8? (and you've not upgraded to Snow Leopard yet?)
If your Licenses are on your dongle already and it's just VI that won't open,,,,,, have the plugins registered OK in Logic plug in manager? Do the Standalone versions open OK?
