i open the program go to file and when i press open the program stop working saying that the program has stopped and then close.
everything else is fine. i installed the program again but the same.
the same program work without a problem in other computers.
i think it started when i was trying to creat a calendar(visual), in order to use Calendar ActiveX i had to registry the computer(don't know if i said it right,i'm new. i just followed the book isntruction).

what version of Windows are you running?

Unregister that ActiveX control and try to open the file again. If it works then there is probably something wrong with that ActiveX control.
