Not sure what you mean here Mark. There is no version 4.8 for mSecure in any app store. Are you referring to the star rating of the app and not the version of the app?
What do you mean when you say it screwed up your back-up? If you can describe what's happening, I should be able to help.
I'm not sure what type of second-rate organization you are running here, but I downloaded and was using v5 on my Mac when suddenly it screwed up my back-up. Now, even the App Store only offers v. 4.8. Are you all going to get your shit together, or what? If not, tell me how I can use my mSecure file with a more intuitive, hopefully better, password management tool.
