nevermind i solved it, it opens now

the map i saved as mapname.map got changed to mapname.bax that tell you anything?

yes it is

in that mapping tutorial it says to make a text document and save it as mapname.bat which i did and the i saved the map as mapname.map..so in the end it say to click the batch file and press any key but when i click to open the batch file i see it for 1 second then it dissapears does anyone know how to stop that?
