Hello I have a problem with a Wifi Survey app, this app is from Access Agility, however this app was working fine, but without advise stop of working, I tried to open again, but app be close after few seconds. Every time that I tried to open it, in diagnostic and use create some files, in special one named LatestCrash-WifiSurvey.plist, this one generate an incident identifier E73B0164-CDFA-4E9E-839E-A0C021BD17A2, but this incident identifier change every time that I tried to open, the last incident identifier is: DE600EB3-AB57-4C33-8DE8-71F6788A7441.
After of it, I checked that the app had a new version available for downloading, I took a backup of my ipad and then upgrade this app, but is the same problem, all I want is to save the projects I had in this app, I´m afraid that if I delete this app and re-install it, probably I loss my projects.
Thanks for your help indicating how I can save my projects and see them for example in an iphone for assurance that data is not lost.
Something that called my attention is part of the log that shows a big CPU processing, but the strange thing is I killed all applications.
