Following are ways to troubleshoot this business connector issue.
1. If you are doing remote development(i.e. on a server e.g. Win 2003) with VS2008 and AX , then make sure you have valid AX client session with same user you login in VS2008.
2. Check under Administration–> Online users that you have session for “Business connector” user.
3. If you are debugging in AX through VS2008 make sure AX Debugger client session open before running breakpoint.
