Hi,

I suggest you to try the following steps, one each time:

1) Reinstalling the add-on using the REPAIR option, or;

2) Uninstall the add-on, clean all registry data [start > regedit.exe (run as administrator) > CaptainSim > 767CAPTAIN], restart PC and install it again, or;

3) If the problem persists, maybe your installer is corrupted. Download it again and try installing from the new installer, or;

Check-in to Customer Support > Select product > Extended Download Service > Get New Links

4) Or if it still doesn't work properly:

Check-in to Customer Supportthen click Product Name > Customer Support > submit a Ticket.

Hope this helps.
