EQ2Map is not being used by EQ2

[Morgian]

After reading the FAQ and some postings, which didn't help me, I'll have a go at it:
- I downloaded the auto-updater and let him install the mod.
- I started EQ2 from the updater and because I have not played EQ2 before, nor seen the map mod in action, thought it was working. It was not, I only get the normal EQ2 maps. I noticed that after visiting Fallen Gate and seeing no map (but thought I should).
- I checked the install instructions on the EQInterface website and everything seems to be where it should be.
- I downloaded ProfitUI (which includes the maps) and drew another blank. The UI sems to be correctly installed, and the INI file points to it. But when trying /loadUI in game, the only interface I see is "default".

So somehow EQ2 doesn't recognize that there are mods present. The question is, how can I get it to do so?

(I run Vista, and no, you don't need to tell me that I should start in admin mode, and aside from this problem EQ2 runs fine.)
