Hi Peter.

I am sure I cannot help you with your particular problem, but...

Here is where I can say something. What do you call "uninstall" and a 
fresh instalation? Did you just uninstall everything and then reinstall 
everything?

This is not enough for a really "fresh" installation, because the 
Nutconf program leaves some stuff in the windows registry that is NOT 
deleted when uninstalling. Thus, when you install another version of 
ethernut, nutconf will find the stuff left in the registry by the older 
Nutconf. Got it?

So, if you really want a fresh installation you have to delete the entry 
in the registry of windows before installing anything.

So:
-uninstall
-clean registry
-install newer version.

How to clean the registry? Just in case, one simply way is to go to a 
command prompt and type "regedit". In my computer I can find the entry 
under HKEY_CURRENT_USER->Software->egnite
Then you will see a "NutConf" "folder". Delete that one.

Yep, you should see me before and after I realized about this ;-) ... 
although it is "documented" in 
http://www.ethernut.de/en/software/nutconf.html (it took me long to find it)

Anyway, just wanted to point out about this "detail" that has caused me 
so much problems, just in case. As the documentation says, -"when 
everything is a mess, clean the registry"-. That helped me with weird 
problems.

Good luck!
