NOTE: Marcus Camillus has created and added to the auto-installer(RTR Platinum v1.5 Patch) a "campaign_map_reset.bat" batch file that will automatically run after the patch install is complete. So, the auto-installer, after it completes installing the files of the patch, will ask if you wish to run the "campaign_map_reset.bat" batch file. If the option box for this is left checked, the batch file will automatically run and delete any map.rwm files in the following places...
* Data\world\maps\base <<============================= Location for the "map.rwm" file with RTW v1.2 patch.
* Data\world\maps\campaign\base <<==================== Location of a possible "map.rwm" file.
* Data\world\maps\campaign\imperial_campaign <<======= Location for the "map.rwm" file with RTW v1.5 patch.
If however you have installed your patch in a different folder(then the one containing the game) then you will have to manually either look for and delete any occurances of the map.rwm file(as described at step III. of the guide), or manually start the "campaign_map_reset.bat" batch file by double-clicking it.
