Sitemap address and contents on wrong server

Another question for your excellent support team :wink:

I recently changed the domain for a site on a multisite (now: aeeactioncamera.nl) and I think that almost all the quirks have been ironed out. However, I keep having an issue with InfiniteSEO...

The site map still gives the wrong address (www.aee-eu.nl/sitemap.xml) and the contents all still refer to the old server...

As soon as I add a mapped domain (I still want aee-eu.nl to redirect to the new domain) all the Permalinks change over to see-eu.nl something I do not want...)

Regardless, the site map remains at http://www.aee-eu.nl (note: with 'www' in front...)

So my questions are:
1. How do I correct the site map address and contents?
2. How do I make sure that a visitor that enters are-e.nl ends up at aeeactioncamera.nl, and not the other way around...
