Yes, I did restore my settings backup - that might be the reason.

For the Navicore part that was discussed earlier: I had the Navicore icon there on desktop but when clicking it, nothing happened - so it didn't open even any dialog to type in the licence code. Having read a while ago the other thread about Wayfinder/Navicore/Map app I assume that they're all the same product. So I guess I'll try to switch back to OS2007 and install the newest Map appliacation, see if it works, and put in my licence code to see if it opens the routing features as presented in the Navicore Personal. If not, I'll just install the original version - or call to the customer support

Thanks to all for the comments, anyway.
