Solved: TypeError: startView() takes exactly 1 argument (3 given)

[Ron Croonenberg]

ok, problem solved.

In the directory the plugin lives I have(had) a directory called 
'backup' to save things just in case I mess up.

Guess what, RB apparently looks into that directory too and uses the 
class, py file, it finds there instead of the one I am making changes to.
