VBA Errror Message "Cannot run duplicate macro!

Hello I am calling a VBA Macro from Menu Bar using following code in "Custom Menu Config" Code file
--Call oMenu.AddMacro("Siemens_MV_Switchboard.Siemens_MV_Macros.Main_Siemens_Swbd", aucMenuToolsOnly, , 0, 0)

Up till now it was running perfect for more than two years.

Now all of a sudden I am the ONLY one getting this error message as shown below.

Errror Message "Cannot run duplicate macro!
"Siemens_MV_Switchboard.Siemens_MV_Macros.Main_Siemens_Swbd.

I checked "Custom Menu Config" Code file. I do not see anything incorrect. and I also did not made any changes recently to this "Custom Menu Config" Code file.

Exactly same situation working fine in Ebase Production Database. and I am the only one getting this error message in Development environment of EBase

Please advise ...what is the reason behind this error message and How can I resolve it.

I will appreciate your support
