Problem with making my custom map VV compatible

[Sute]{h]

I'm trying to get my Exalted map to run on VV, but I get the following error message, when the game reaches "initializing map logic":

"exception in: .\discfile.cpp, line: 425. Description: Could not open file:"

I think the error is related to the new regions in some way. So far I've only made a new region.txt containing the regions of my map. So I havn't edited localisation files yet or anything like that. Obviously I'm missing something to get this thing up and running, but I don't know what though. The mod was working fine before VV, so it have to be related to the new features in VV somehow.

Any help would be much welcome.

I found the problem. I forgot to add region="region.txt" in default.map.
