Hi Kishan,
You might want to go to www.snowcovered.com and login there and look up and download any patches/fixes for Dynamic Registration 4.0.50. This is not the latest release of the module and some customers will upgrade when they are not using the latest releases as we don't correct bugs in the older versions as we go forward. The current release is 4.1. Also look at:

thanks
