So a few days ago my WL app (Android) failed completely and didn't open. After about a week of this I decided to give up and try re-downloading it, but now it won't download.

What the f*** were the app creators thinking?

How much free space do you have on your phone?

I would recommend having at least 100MB free. The game is 28MB but maps and other data can be another 15-20MB more. If you phone is running out of room that could be an issue in general.

Also, what is the error message you are seeing when it fails to download.
