I have created a class that is used to send email. I use this in almost all of my applications and have never had a problem w/ it until last week. I am getting the following error message:

Error #430: Class does not support automation or does not support expected interface.

Can anyone give me an idea of what I'm doing wrong or what happened? The problem doesn't occur on all PC's, so it is really puzzling.

I'd appreciate any help.

Regards,

Chris
