To day I have tried to update the firmware on my XW-P1 that I LOVE - what a instrument . But I get problems with the update. I downloaded that who should be the new 1.11 update from 18.12.2013 from Casio support site (see pic0). I turned of my AntiVirus software before I start downloading and followed the instructions one the same page. At step 5 in the instructions I get problems: When I "Double-click the update program" I get following error message: "XW-P1 Updater.app" is damaged and can't be opened. It should been moved to the Trash Bin (see pict1 - its in Swedish). When I open the info panel for the XW-P1 Updater.app in Finder, it says that the file is last changed the 28 may 2012 (see pic2). Is this really the newest firmware of this file? I restarted my Mac and XW-P1 and have tried 5 more times before I write this Topic. What is wrong? Is there someone that can help me? Thanks in advance /MigthyThor
