I have been using Live mail "forever" but since my provider TDS switched from gmail hosting servers to their own tds hosting servers, I get this error. It stopped for several months but now is back

EVERY time I try to open an email, I get this error, but then the email IS open

EVERY time I try to send an email  get the same error

EVERY time I try to refresh (send/receive) emails I get the same error

I have 2 email account in Live Mail:

TDS and Hotmail. The Hotmail NEVER has this error; TDS constantly

I run WIN7 Home Premium on Desktop

I run WIN7 Professional on Laptop

My husband runs WIN7 Home Premium on Desktop

We BOTH get this error therefore I have to believe it is TDS's problem causing it

I checked memory and these are the numbers for my desktop:

Total              8102

Cached          3802

Server Response: Your IMAP command could not be sent to the server, due to non-network errors. This could, for example, indicate a lack of memory on your system.
