Unable to read Hotmail Emails


New Email
I have been with hotmail since 2006 and I have been recently emailing a lady about something for a few weeks and just the other day I noticed that I could not open the email she had sent me. I can log into my hotmail account perfectly fine without any problems, but it is only when I click onto the email message to open it, a pop-up warning sign says "Hotmail wasn't able to complete this request. Microsoft may contact you about any issues you report". Help please.:confused:
