Debugging COMException - com

Question

I am using an ancient Intergraph routing library to do some routing.
I could create several ActiveX and COM objects just fine but there is this one type "Location" and "LocationCtrl" that throws a COMException on creation.
Here's the relevant code
_sourceLocation.Streets = _streets;
_sourceLocation.VerifyAutomatic = fa_sourceLocationse;
_sourceLocation.VerifyType = VerifyTypeConstants.VerifyUsingA_sourceLocation_sourceLocation;
_sourceLocation.ReplaceTextAfterParse = true;
_sourceLocation.ReplaceTextAfterVerify = true;
_sourceLocation.Map = _mapOcx;
The COMException was thrown upon setting the Streets property.
Here's the exception:
System.Runtime.InteropServices.COMException was unhandled
Message="Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))"
Source="mscorlib"
ErrorCode=-2147418113

InnerException:
The entire application is extremely simple, it contained only code that initialize some of the supporting objects, however this particular Location type would initialize just fine but on first invocation of property getters/setters, it would throw the above exception.
I have been debugging this for a few days already and havn't found a way to instantiate and initialize the Location class properly.
Any clue? Some pointers on how to further investigate this?
