Cannot create a new application

[Ray]

Hi, 

I have 2 problems. First I registered a domain last year through google appengine and entered my credit card details and checked that google automatically charge me for the next domain renewal. but I got an email two months ago from domainsbyproxy.com saying that your domain name is on sale and you can buy that from us. I first thought that's a fake email but when I check the whois I found they acctually own the domain. My bank account was/is correct because google is charging me for the appengine's services (bandwith, process...).  I tried to contact Godaddy and google butno luck. My question is can I get my domain back or can I rely on google to register another domain with them?

My another problem is I cannot create any more application on google appengine. It doesn't show any error message. The application just doesn't appear on the applications's list. I still should be able to create 6 application. 

Thanks in advance for your help
