I just bought a blackberry 7130e, and when I link it to the computer and try to have the messages go through my computer it gives me an error message. It says that, "The computer does not know its message account address. Either the messaging system is not configured properly or this messaging system is not supported." Any help would be great.

Thanks.

First, welcome to the Forum.

You cannot sync mail and messages on a pesonal BIS setup via Desktop Manager, if that is what you're attempting.
