A possible solution for 'stringtable error'

So this is what happened to me . I followed Myrddraal's mapping essentials exactly , and he said to copy the imperial_campaign_regions_and_names.txt file . So i did it , and called it my_campaign_... . Then , after finishing it all (i made 1 extra region in the desert , so no mountains , etc..) , i went to test my brand-new campaign . But i was kicked back to the Provincial_campaign menu . So i spent lots of days trying to figure out what happened . i saw a tip from a member who said to rename or replace your my_campaign_regions_and_names.txt . So when i deleted it , i saw that beind the file name , the word - copy was placed (because it was a copy ofcourse.) So when i deleted that "- copy" behind it , problem was solved .

So , to sum up , check if the word "- copy" (or kopie , it all depends on your language ;) ) isn't behind the file's name :)
Then ofcourse , delete map.rwm !

I hope it works for you like it did for me ;)

Happy modding!
