I am trying to download a new theme from app world and I keep getting an "Unknown Error" message when it tries to download after I have paid. I know it is not just the theme being messed up as I tried downloading a few other items and I get the same message for them all.
I have tried pulling my battery, and re-installing App World as well. I know normally I can download from it as I have done it just a few days ago.
Does anyone have any other suggestion as to what I can do. Thanks for any help.
