Why?

I clicked on the 'Business' tag at the top of the page while in the perpsonal version of Zoho and now appear to be permanently stuck in the Business Version. Does this matter? Have I exposed myself in some way? Why was I not given the option to go back? Why can I not change it back to personal? Despite sending a message to the powers that be, I have had no response. Perhaps someone here can help or advise?
Thanks
