I had the same problem also. but when i clicked [ok], what ever i clicked before opened. i downloaded route builder in my opinion, i regret it. u maybe might understand it better than me but i prefer coding by hand. one of the codes that will be hard for u to remember is the station coding. this file is on this webiste and all u need 2 do is type in the compenents u need, click submit, and u have ur code 4 a .csv and a .rw file. i consider coding in excel better. but REMEMBER 2 save in .csv or bve can't open it in the developer's zone,
