I am getting errors on corona simulator I didn’t get before the iOS 7.1 release.

Attempt to index global ‘highscoreFile’ (a nil value)

local function open()

highscoreFile = io.open(system.pathForFile(“highscore.txt”, system.DocumentsDirectory), “r”)

highscore = tonumber(highscoreFile:read("*a")) <THIS LINE! IS 621

highscoreFile:close()

highscoreFile = nil

end

I prefer to use a preference.lua from Sateesh

How I save Preferences

preference.save{PrefVer = "1"} preference.save{PrefLastLoadTime = tostring(os.time())} preference.save{PrefLastSaveTime = tostring(os.time())} preference.save{PrefLastSync = tostring(os.time())} preference.save{PrefFunc2UpdateFreq = "60"} preference.save{PrefTimeZone = "AEST"} preference.save{PrefTimezoneOffset = "11"}

How I load preferences

preference.save{PrefLastLoadTime = tostring(os.time())}

How I Clear All Preferences

local function PreferencesDelete() DoPrint("PreferencesDelete()") local destDir = system.DocumentsDirectory -- where the file is stored local results, reason DoPrint(" Deleting Old Preferences") reason = os.remove( system.pathForFile( "PrefVer", destDir ) ) reason = os.remove( system.pathForFile( "PrefLastLoadTime", destDir ) ) reason = os.remove( system.pathForFile( "PrefLastSaveTime", destDir ) ) reason = os.remove( system.pathForFile( "PrefLastSync", destDir ) ) reason = os.remove( system.pathForFile( "PrefFunc2UpdateFreq", destDir ) ) reason = os.remove( system.pathForFile( "PrefTimeZone", destDir ) ) reason = os.remove( system.pathForFile( "PrefTimezoneOffset", destDir ) ) return true end

Put this at the top of your code.

local preference = require "preference"

Save this to a file called preference.lua

Max, that shouldn’t have anything to do with 7.1. There will be more details in your console log. Please look there and post more information here.
