Hi everyone, I had a very bizzare situation happen yesterday. I haven't discovered what caused the the problem though. Here's what happened. Wednsday, I downloaded the Beta 1.9 but didn't install it. Thursday I ran software updated for my dual 1gig Quicksilver mac to update my OSX Panther software. However, when I launched Logic Platinum 6 and installed a MasterX5, my meters which are normally green and yellow were completely showing white. I tried to "Refresh Audio Unit Plugins" from the 1.8 installation file but nothing changed. Tried reinstalling permissions and repairing permissions but it didn't correct the problem. However, my MachFive AU, and my Oxford EQ disappeared. When I tried to reinstall them, I would get a white splash screen that only said continue. I'm not sure what may have caused the problem either the 1.9 Beta or the OSX updates that were installed. It forced me to reinstall my OSX Panther software. I then ran software update again to update OSX Panther but stopped at the latest Security Update, iSynch Update. I'm wondering if the latest Security Update gave me a problem alsol. Upon doing this Panther created a "Previous Systems" folder that I was able to copy my AU plugins and PowerCore plugins to there perspective places of my new OSX install. I also had to reinstall my 2408MKII's PCI-424 AU driver and MOTU USB driver for my MidiTimepiece USB AV. All is well again. Anyone else experience this madness? Randy
