map.rwm files empty.

[FOR GONDOR]

So I installed RSII but whenever I start a campaign I get as far as the load up screen to go to the actual map of the campaign, I did a little digging through my files, for all the campaigns, like "Play_Sparta" the map.rwm files is empty, as well as the map_ heights.hgt file for all the campaigns, as well as for the base data file fir RSII, would be at all possible for somebody to say email me said files i need

From TWC Wiki:

map.rwm

A map.rwm file is present in the data/world/maps/base folder when you install Rome or Medieval II - Total War. One will be in the bi/data/world/maps/base if you have Barbarian Invasion installed. The map.rwm acts a little like a saved game file containing compiled information from a variety of map tga's and text files.
If you wish to make changes to the campaign map you need to 'delete' the map.rwm file (just re-name the file to xmap.rwm or similar so game doesn't find it and you still have copy). To make changes affecting coast-line you will also need to delete (or preferably re-name) the map_heights.hgt file.
[edit]Re-generating the map.rwm

When you start a new campaign after deleting or re-naming the original map.rwm a new one will be created for you. The new map.rwm is created after you select a faction to play campaign as and select arrow to load campaign, it will take longer to go through screen change and loading bar than normal while the new file is being created.
If your game crashes when the new map.rwm should be being created (and it is not created) then you have some error in the modifications you have made. In RTW that can include having too much sea area (the so called Landmass Crash) - having rivers incorrectly drawn in map_features.tga, some gross discrepancies between map_regions.tga and descr_regions.txt and other causes..... Most of the errors that result in a failure to produce a new map.rwm do not give a -show_err message but it is always worth having that on your shortcut anyway.
Note that the map_heights.hgt file does not re-generate and is not strictly required for most game versions.

I Suggest a Re-install.

It's basically covered in the previous post.

The map.rwm file is created from other txt files that are in the data folder when you launch a campaign so long as the file does not already exist- I'm not sure which files are needed to do this. It's perfectly safe to delete it - in some cases the map.rwm file becomes corrupted and deletion is the best way forward (which is why the launcher usually does it for you).

So, the file is pretty much redundant in that you don't need it to be there when you start a campaign or load one up.
