hello, I received this message when trying to read my mail: Your default mail content not properly installed. what does that mean? How do I fix it?

What do you use to open email messages?

Outlook Express?

Thunderbird?

It means whatever your using for your email client is either not there, or is not properly installed.

Also what exactly are you clicking on when you say "I received this message when trying to read my mail:"?
