Freeze in time "Processing weather data"

Hi!
I use Glofiish X500 with WM5. To connect PDA with internet I use WiFi or ActiveSync.
WWM (1017) worked very good for many weeks, but stopped last friday. When I update informations, it downloaded data, but freezed in time “Processing weather data…”. Freeze only this application, whole device work correctly, but I have to restart it to close application.
In time of failure I don’t instal or remove any applications. Reinstallation WWM don’t help.
Have enyone any suggestions?
Thanks
