Undesired login - post 2 - private link not working...

Sorry I am not responding to the previous post "Undesired login", but the forum will not let me post a reply (I tried twice - and it would not show up). The last post asked for me to send in my iframe link. I have had the following private link working for 4 months. Recently, the private link brings the user to a login screen. Here is my iframe:
<iframe height="500px" width="100%" name="zohoview1" frameborder="0" scrolling="yes" src="http://creator.zoho.com/showViewLinkAlone.do?viewlinkId=1&link=false&sharedBy=jleona&hdrClr=fc7802&bdrClr=fc7802&privatelink=wwPwrmNpKKk6y7tjmxFPdvFuwDmv6S0Dzpk3E7OQmxmJ00kzxqY1ym3UrWPet9uOJXREZfHKxHMTgqQGu0N7MbRkHjQPW8zBFzaM"></iframe>

Please let me know where i can assit with the troubleshoot.
