Hi @eric3620 and welcome.
I'm really sorry you're having problems with your email. Can you take a look through the link posted by @gg30340 and let me know if that helps. If you're still stuck drop me over an email with your details and I'll take a look at this for you. You'll get the contact the moderators link in my profile.
I have tried to but my details, ********@btinternet.com are showing that the account does not exist!
Even though it was working correctly up to 9 days ago.
Thank you, Eric
