Tridion 2009 SP1 TcmUploadAssembly not able to overwrite existing TBBs

Question

I am using the TcmUploadAssembly utility in a post-build event but am receiving the following error from the tool.

Error 1 Name must be unique for items of type: Template Building Block within this Folder and its BluePrint context. Source or sources of conflict: tcm:5-200-2048. C:\Projects\Project1\src\Tridion\TBBs\EXEC Compound Templates

The TcmId given refers to the Assembly stored in Tridion which I would expect because that is what I am overwriting. In the past this "just worked". Am I missing something?

Notes:

1. My user is an admin
2. The Tridion instance is on my network so I am using credentials in context.
3. I have specified all settings via the command line (no config.xml is used)

Any ideas?

I would say check your Blueprint context (i.e. the Publication you are in). This error means you are trying to create the TBB, yet there is already an item with the same name probably somewhere down in the Blueprint child Publications.
