Since support seems to be extremely slow here I did a bit of digging.
I solved my issue by disabling a 3rd party module I was using. RSocial was calling for an external script that did not exist that prevented DT Register from loading its jquery script. You can kind of get an idea of what script is not loading by using Chrome web dev tool and inspect element and see where the error is.
THere still is a problem with the display of attendees "Unknown column 'orderByJoin2.firstname' in 'order clause'" and the front end imaged not showing that are part of the problem with the new update. But at least the registration forms are working now for me.
