PC Suite problem - please help

My phone is a Nokia 6800. I have been using PC Suite 6.1 to send and
receive texts. I occassionally get sending problems (message sending
failed) but what I do is send another message and this usually
"pushes" the other unsent messages in the outbox. If this doesnt work,
i uninstall/reinstall pc suite and it works again.

Lately however, none of these remedies work. I can no longer send sms
through PC suite.

Please help.

Thanks/ Gio


my PC OS is Win2000
