copy express addon is not responding

Hi experts,

When I am trying to copy master data from one database to another database by selecting all check boxes in Data Categories, the copy express is not responding. With out selecting the master data it is working properly but master data is not updating.

My requirement is to update the master data from one database to another database.

Please give me suggestions, what I have to do.

thanks in advance
