Windows 7 - Macrium free backup won't end

Every time I do a system backup it progresses fine until both progress bars get to
Overall Progress 99% and Time remaining 01 second. It continues to run as long as I allow it. Finally after a half hour I click cancel, but it still continues to run so I have to do a hard shut down to end it. This has happened twice before in the last two weeks. I thought something might have gotten corrupted so I uninstalled Macrium Reflect Free and re- installed it fresh doing an initial backup, but It still won't end. Does any one know what's wrong? Thanks in advance.

Here's an edit to the above post. I didn't mention that the first 5 backups since I installed Macrium free went OK. Recently there was an upgrade to Macrium Free which I downloaded. Could the upgrade be the culprit? When I reinstalled as mentioned above, the upgraded version was installed. Could be something, or maybe not. I'm new to imaging so I don't have any ideas.
Perhaps WHS or another learned person can help me. I see 38 or so people have read my post but don't have an answer, so I'm getting nervous that I might be SOL. :-)

Hi all, May I appeal again to any one who can answer my question in my post above. Thanks in advance.

Heyyou, I don't think I can answer your question. I use Macrium free on 3 computers and have never had that issue. It has always worked well. I have installed the new update and have no issue with it other than the advertising. When you reinstalled it, did you go back to Macrium (or CNET I guess) and download it again? I believe I would try that. It's possible the download was not correct.
