Greetings. I bought a 21.5-inch, Late 2009 with Snow Leopard. The application Osirix for medical images invite me to upgrade to Lion. Consequently The Superdive stopped working and also LAN. I find that Apple is aware of it. No response or timely support. I can not return to snowleopard with the installation disk  not reading.  the hardward test that do not   come with the version of Lion download from  the internet. I can not use the Hard Drive Test remote internet because LAN is not working.  Pleace tell me what is the best way to get the superdrive and LAN working again: back to SnowLeopard?  Is there at Apple a fix that I have not seen?

thanks
