All of a sudden program won't open.

You made a post to the General support. Are you referring to the general Web service or something else?
Please clarify on what you mean by "won't open" or provide a screenshot if that's easier.

Thanks for responding.

When I click on the Mybidder icon nothing happens.

It has been running great for over a year so this just started.

You still did not answer my question.
Are you clicking the icon in your browser?

Please feel free to provide a screenshot if that's easier.
