Hi Flavio
1.2 Beta doesn't solve the problem. I get exactly the same error message, still no possibilities to perform a single measurement.
(and i am on a standard iMac, latest OS, running through standard iTunes into standard airplay).
can you still help ?
and maybe talk to Dirac helpdesk, as I did not get a single reply from them within 2 weeks. and I am really interested in the product.
:-) Philippe
