Striata Reader - Content expired

Issue
I get a message like the one below, and I'm not sure what to do about it. I do know that the attachment is not useable.
Content expired

Explanation
The sender of the message has set an expiration time for the emc attachment. This means that the attachment can be opened for a limited time after sending. The attachment must be opened within this period. This functionality is useful for time sensitive information.

Solution
You need to have opened the attachment within the time limit set by the sender. The error message is generated when you attempt to open the attachment outside the time limit.

For example: the sender sets the time limit to three hours and sends the message at 7am. You have until 10am to open the message after which the attachment automatically expires.If you really need the attachment, then you need to contact the person who sent you the message and asked them to re-send it.
