I have been using gmx.com for months without any problems - until today. When I logged in and requested mail the usual screen came up with the message "loadingGMXMail" but this time it just KEEPS going. I have retried several times today with the same result. So I tried sending an email to gmx from yahoo and that failed because the mailbox is unavailable. As I cannot contact gmx, what should I do?I don't know.  Works here. GMX is a very RELIABLE service and I am surprized that is stopped working for you.

On a HUNCH, see if you can open their site using a proxy. Once in awhile a few  IPs on the INTERNET get choked off by some local service providers.  I joined GMX in my daughter's name and it worked fine until I requested mail when the same problem occurred.I was using FIREFOX when this problem occurred. I have just used Internet Explorer and the problem disappeared. So Firefox was causing the problem for some reason, unknown to me.I have reset Firefox and the problem has been cured. But I have no idea why it happened. Thanks for the help.Thanks for sharing. This may help others.
