Jevents not working properly

i am using 3.4.3 version of jevents and every event i create doesn't matter what day time i put is says registration is closed. also when you create an event from the front end the calendar repeat option doesn't work wont let you pick a day till you want it to repeat till. Also in the attendance option when you click on the watch icon to adjust the time that also doesn't work. please advise. I am not sure if this a technical issue or a bug. thank you for all your time and help.
