I updated to 2.7.2d and installed the new plugin (plg_jeventupdate1_5).
So far, many issues I was having, such as times not being synced properly between JEvents and DTRegister, and not all JEvents appearing in the DTRegister New Events drop down list, and DTRegister not linking with the correct JEvents entry have been solved with the use of this plugin.
I had to open each event in JEvents, reset the event times, and resave for the plugin to work properly.
The reason I still use JEvents is that over 100 previous events are carried over to this year, with changes only in dates. To be able to continue to sync JEvents with DT Register is very helpful at this time.
