Upgrading DL.2 to 1.5 question...

Hello, I had an issue with uploading content to my three DL.2's yesterday via my Apple MacBook Pro after updating to OSX "Snow Leopard". I updated my CMA software to the newest BETA version that is currently available for Macs and when I try to import custom content, the status bar still appears as if it's about to receive the content, then it disappears and the content doesn't actually load. I think what I need to do is upgrade my DL.2 fixture software to the newest version 1.5. My question is, how do I do this and what are any possible repercussions for upgrading the fixture software?

Sorry this is so lengthy, but any advice is appreciated!
