Cydia doesn't refresh Data
hope anybody can help. When I open Cydia on my Ipad (JB 3.2.1) I can after a few seconds the following error message:
error: Refreshing Data
GPG error: xSellize
Release: The following signature were invalid: NODATA 1 NODATA 2
Failed to fetch
returned an error code (2)
Some index files failed to download
they have been ignored or old ones used instead.
Since then I can not get any updates from cydia etc.
Any idea? I don't have a clue.
THanks a lot
