Hyperlinks

My calendar is totally public, but when I try to embed a hyperlink -- just a plain old garden-variety hyperlink -- in my wordpress.com site, it malfunctions and takes the user to the Zoho home page and asks for a login. I've tried the string provided in the settings for hyperlinking. Failing that I tried both the embed code and the ical URL.

What's up with this calendar and how can I make this displaying work? I AM able to use the ical feed to create wordpress event list shortcodes, but I cannot do anything with the calendar, and I would like to show it to my users.

my login is uuauctionweb.
