TOPIC: Creating a link to a specific event registration

I have just upgraded dtRegister on a Joomla 1.0.15 site to 2.4.6. In the past I could create a component menu item select the event I was interested in, copy the URL and then create a new menu item as a link-url and have a menu item go to the the specific event registration form. After having upgraded and doing the same thing when I click the menu link I get to the page that is supposed to confirm all of the entered information but it is 'blank' if I then click the 'back' button I can then fill out the form and proceed. In looking at the URL's they are identical between the two screens. Is this a javascript issue? If not how can I create a menu link to a specific event registration?

Nevermind, found the solution. I think that the URL had too many characters and Joomla 1.0.15 won't store more than 256, so I just eliminated the [url=http://..]http://..[/url]. and started at the /index.php
