the meta.txt is necessary to activate the map , no matter what tool you use
in EasyUseTool you must copy it in in the text file that is already there , so the tool can read it
mind you , its not just text , its a code
try to read the "read me not" which came with the EasyUseTool , it explains it all ( not easy but still )
the meta.txt is a bunch of digits , you should be able to find
if not in map-forum then here
