Heavens-Above - PDA sync problems

Hello everybody,

Have you recently experienced any problems with syncronizing satellite
predictions on your PDAs with the use of H-A's AvantGo subscription channel?
Some days ago something went wrong with my list of sat predictions - it
simply fails to synch properly. When I try to access the channel on my
device after I synchronized it via MS Activesync, I'm only directed to the
initial welcome screen, where I'm asked to provide user ID and password and
sync the device in order for the changes to take effect. Yet, nothing
happens after the synchronization - I simply get the same welcome screen
over and over again. Another strange issue is that I hadn't modified any
settings concerned with the channel before the synching problem appeared.

Has somebody got any idea how to fix this problem?
