Y!Mail not working

[Ceymore]

Hi All,
Yahoo mail has stopped working on my Nexus7, been working fine until now.
It loads up and displays all the mail previews on the left of screen but on the right of screen where the email should be the display is blank purple, no message display no matter what I do. I've tried uninstalling and reinstalling the app but no difference. Everything else on my Nexus works fine.
As far as I know I haven't altered anything.
Any help muchly appreciated.
Cheers
Cliff

Try resetting the app's data - find the app on the "All" tab in Settings -> Apps and click on "Clear data". You'll need to enter your mail settings again as the app should now behave as though it was newly installed.
