Mi Amigo !
Sorry you have been in email-he-_ _ for a bit - I cant think of anything worse - especially if you use email every day like I do...
So, when you lost your email, did you look at the Incoming Server, Encrypted Connection, Outgoing Server, Encrypted Connection Settings and verify they were correct ?
In my experiences with Email, this is usually the only thing that gets whacked out and has to be set again, when it stops working..
Only other thing I can think of is that you lost your email address completely - well, actually, they lost it or disconnected or something like that...
Just went through that nosebleed of having to get a new email address after having the same one for 14 years, and no one should ever have to go through that...
Have never heard of the cable modem etc., going out and not allowing just email either..
It all comes in through the Internet like you already know... Weird....
Good luck !
