Saving information to a File

In my 1.2 created game, we saved the highscores to a file. This all works great no problems.

With 1.3.1 this no longer works (yay lots of fun)... it now says that it cannot find the file (message below)

Adding new Highscore to SimSet
New Highscore Added
Sorting Highscores
saving updated highscores
Saving
getPrefsPath - Filename (../Documents/Castle Software Ltd/Whack Em World Tour Lite/game/scripts/highscores.txt) cannot be relative.

So what has changed? How do i fix this? The original path to the save file is shown below:

Path = getAppDocumentsPath() @ "~/scripts/highscores.txt";

Where do i now save it?

Many thanks

Jason
