If you copy an old conference to your new conference and in the old conference BadgeTwin.rpt is still used, it will cause problems changing and/or printing the badge.
By changing the old badge, you will see the old BadgeTwin.rpt, but if you print you will see the new BadgeTwin107000.rpt.
Follow the next steps to solve this:
Go to the Windows Explorer and search the conference ('\EVWDATA\EVE***\').
Rename the badge BadgeTwin107000.rpt into BadgeTwin107000_old.rpt.
Rename BadgeTwin.rpt into BadgeTwin107000.rpt.
Now the same badge will be used when changing and printing the badge.
Of course it is also possible to rename the badges into one of the following badges: Badgetwin107002.rpt and Badgetwin107100.rpt.
