Full Version making a pit stop

Since making the full version free it suddenly got 800 downloads, after a previous high of say, 4! People love their free apps obviously. I intended to let out around 100 in order to get some more feedback about the data loss situation to report to the developers - 800 is kind of overdoing it! Anyway, I hope you downloaders enjoy the app and spread the word (not with bad reviews about kanji data loss, there'll be a fix soon!)
Background:
The full version has sometimes been having trouble accessing the kanji and progress data from an external file. Hopefully this will be fixed very shortly ith an update. In the update I will also include in-app help info, lower the sounds, edit some data, and set the loading default to 'random'. Any other quick edits I should do?
If you are experiencing the kanji/progress loss situation, please leave feedback below, with the basic specs of your device.
