Hello again. I have LogicStudio 9. It is version 9.0.0. It is installed and working. The 9.0.1 update doesn't show up in my Software Update dialogue box (the recent iTunes update did). I downloaded the 9.0.1 updater and when launched, it tells me that the update "isn't needed". It won't let me install the MainStage 2.0.1 update either. I repaired permissions btw. Any suggestions are welcome. Thanks in Advance folks.
