Aha, hi there Hilton!
Hope you're still enjoying your adventure.
I had a quick look at the differences between V9 and V2008 of CN Europe and found the following:
For Slovenia, as you saw, the coverage on 2008 is much improved
For Croatia, it looks much the same on both
For Serbia, and this is really strange, it seems that the base map for version 9 actually has more detail than the now selectable regions on version 2008! Very strange . . .
Here are some screen shots so that you can see for yourself what I mean:
