It might happen that something does not work as intended. We would like to help you the best we can, but for this we will need some information first.
In case there is any error pop-up, please screenshot it and send it to us. Also, describe as well as you can when/how it happened (what did you do or click prior to the error/malfunction appearing).
This will let us see what might be the cause of it and then we will be able to give you proper troubleshooting or ask our developers for assistance.
