500 Internal Server Error

I login to DG and am getting this error. I was editing my articles at the time,
and on hitting save changes, the screen would go to a login screen,
with 500 internal error message. I have lost the same story 3 times.
Maybe the computer doesn't like my story?

Last night, after I hit save changes, it went to a 500 internal server error
screen again, but this time, I had a german sentance across the top
of the browser telling me in german, that it couldn't find the article nor
does it think the article ever existed.

I wrote to Dave and Terry, and they are both saying I have a bug. I ran
Norton 360, nothing found. we keep this computer in tip top shape
and I am forbidden to download stuff. we also run a spyware continuously.

I have not tried to do my article yet, tonight. Its getting tiresome!
I thought a 500 internal error message is strictly from the server, and
has nothing to do with our computer.

does anyone want to help me out on this or have some thoughts?
Thanks,
Sheri
