am downloading the ones from here as we speak, did have the extension enabled, and according to the literature I read, my g4 (dual 500mhz) 1 gig ram , should have (and had at one time) no prob running it (in OS 9), something got messed up in my OS X or 9 folder , so when i tried it on classic in OS X, there was no way, i just figured if i couldn't make 5.1 work , i could make 6.x work in OS X tiger.now Im sitting with a lot of hardware and no way to use it, 32 tracks of 24/48 pro tools mix gear, and a g4 thats no help....and , it says that when using nine, the dual procs don't really matter as its only using one....and thanks for the plug in links as well, once back up , I'm sure i will use some, some i had....any not there that i have I will post
