Sync Failed! Account Expired!

I’m locked out “Sync Failed! Account Expired!” since around 7/23/10. Sent a email to Nozbe and Delfina replied “Yes we are aware of the issue and the developer is working on it. Meanwhile the only suggestion I can make is reinstallation of the application. I’m sorry for the inconvenience.”
I replied with a question: “If I reinstall the app will I lose my Nozbe data on my iPhone?”. No reply, I have repeated the Question several times and I get no reply.

I need better Customer Service than this, if you can’t provide it, just tell me and I can find another app. I would like Nozbe to provide better customer service. I’m a paying customer!
