i finally broke down and purchased the 8 core mac and oh boy i am MORE than pleased. anyhowz i'm trying to upgrade my Avid Express Pro (Mojo) V4.8.4 to the MC 4.0 software and cannot find a link to purchase a downloadable upgrade. is the upgrade available as a download or is it only a box set update? 

I also assume there will need to be a dongle upgrade?

in the past BLKDOG and Marianna have been quick to respond so i'll thank you ahead of time should that be the case once again.

thanks to all who may help out

Just check the announcement post at the top of this forum.

Actually it's at the top of the MC forum.
