mmaydesign - Hello. First, please do not hijack OLD forum threads, especially when it is not the same issue. your issue (as seen in the error) is that the JEvents database does not exist on your site. You either did not install JEvents as instructed, or you didn't complete the install. You need JEvents 1.5.x installed, then go to that component's configuration and SAVE. That will complete the install and setup the database structure. DT Register looks for that, and this error is telling you that it is not there.
So, no problem with DT Register... just a setup issue Be sure to watch our video tutorials and read the readme file in the package. Thanks.
