Jacob:

In NIMv2 the user interface no longer provides for a username field to
type into so I believe the problem has already been solved.  

However, I would like to ask.  Did you try removing the incorrect
network identity from the list of Network Identities?

1. Choose Options->Identities from the menu
2. Select the identity in the list
3. Press Remove Identity
