OpenBuildings Update 6 Installation error

Hi all,

I have some problems with Update 6. I had installed ABD Update 5 and worked smoothly, and then updated to Update 6, that installed in its own folders, as expected.

Now OBD starts normally, but when I try to open a DGN it gets stuck. Sometimes I saw the "Default.xml can't be created" message, but now I don't see it, I don't know if it is related or not.

As it can be seen in the capture, it seems to be getting stuck when it tries to open the Family / Part toolbar (or the Locks tools), all the rest is opened ok.

I have several other Bentley apps, so I thought it was something related to incompatibilities or error in variables inside de CFGs, but I can't find what is happening and I don't want to uninstall all (by now).
