Error with SPPID's Interop.Llama library : System.Runtime.InteropServices.COMException (0x80000008): No DBConnect for Data_Dictionary

I'm having the following error usiing SmartPlant P&ID (SPPID) automation library Llama (Interop.Llama.dll):

System.Runtime.InteropServices.COMException (0x80000008): No DBConnect for Data_Dictionary
at Llama._LMEquipments.Collect(LMADataSource& DataSource, _LMAItem& Parent, String& RelationshipName, LMAFilter& Filter)

Here is the code that calls it:

Dim objDS As Llama.LMADataSource
Dim objEquips As Llama.LMEquipments        

objDS = New Llama.LMADataSource
objDS.ProjectNumber = Project.SPPIDName & "!" & Project.SPPIDName
objDS.SiteNode = Project.SiteServer

objEquips = New Llama.LMEquipments
objEquips.Collect(objDS) ' throws Exception

Any ideas on what might be wrong?

SPPID is an engineering tool used to develop and manage piping and instrumentation diagrams. Llama is an automation library supplied with SPPID.

This means that your code can't find that specific project in SPPID available plant structures database. Beware that the ProjectNumber string is case sensitive .

In my case, all I had to do was to change project name, from PF2_REF to PF2_Ref (replaced last two letters for lowercase equivalents).
