Clicking cancel, as you did, is the right way to proceed.

I'd recommend to use AVRDUDE, as explained at
http://www.ethernut.de/nutwiki/Ethernut_1.3_H
(Screencast 3)

Right, you need to upgrade the SP Duo firmware to 2.4. See
http://www.egnite.de/egnite-shop/programmierer/sp-duo-2.html
(Download section)
The archive contains a text file with further informations. You may also 
look to

Right again, after erasing the firmware, Basemon is gone. There is a 
Quick Start guide for Ethernut 2, which basically is valid for Ethernut 
1 too:

I assume, that your configuration is incomplete. Note, that the platform 
needs to be specified twice: In the Component Tree under Tools (GCC for 
AVR) _and_ in the settings under Build->Platform.

Try to follow the screen casts on NutWiki step by step. This should work.

Btw. when changing Configurator Settings you not only need to rebuild 
the system, but also create the sample directory again. Don't worry if 
it already exists. It will retain any code changes you may have made in 
the app directory, but simply update the related Makedefs.

May look like this at a first glance, but you are on the right track. 
Mainly you became confused by the problem with the latest AVR Studio 4.
