"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Your attachment wants to open in Word here and is meaningless.

Can you make a screen capture of the actual error and post it here as a PNG or JPG file that we can see?

Is your domain that you are sending from u-technologies.com?
