Hope someone call help me with this:

Website with following modules installed: Effority.Ealo API, Effority.Ealo.HTML & Effority.Ealo.Tabs (Latest version 5.5+)
DNN Version: 5.6.2

The HTML module works fine and I can easily modify the text between languages.
Changing the menu however does not seem such an easy task.
I followed the installation as provided in the readme.txt file:

1. Make sure that the Effority Ealo Core API (DNN Module) is installed. (works fine, since html module is working)
2. Make sure that the Effority Tab Localization Module is installed.  (I'm assuming this is just the Tabs module that I downloaded)
3. Add the "EfforityMenuNavigationProvider" to the navigation provider section in your web.config (done)
4. Not specified in the readme file (missing section, maybe not important, maybe very important, dunno) :-)
5. Change the value of the Attribute ProviderName of the <dnn:NAV ... /> tag in your skin to EfforityMenuNavigationProvider

And it's the last part that gives me a bit of a headache.
- I go to Admin >> Skins >> Skin Designer.
- Select the skin I use from the list
- Select the file & token NAV
- Select Setting: "ProviderName"
- And then I should expect a list displaying me with the option to select the "EfforityMenuNavigationProvider".  This however does not occur.

Thought maybe it was something in the cache so I restarted IIS, but that didn't help either.
Double checked the config file, nothing wrong there afaik...

Any help/hints would be greatly appreciated!
Thanks!
