A) Please, get an a recent patch level such as SAP BI BusObjects 4.0 SP4 PATCH 9. Remember to upgrade the Client Tools of SAP BI BusObjects (such as Webi Rich Client, IDT, UDT, etc.) as well!
SP4 Patch 2 is like 6+months old.
B) Is your SAP BI BusObjects server running on Windows Server or *nix.
For Windows server based platform: did you install a recent SAP GUI on the SAP BI BusObjects Server? And can you then connect using the SAP GUI on your SAP BI BusObjects server to your SAP BW System?
