i cant seem to get my roller coaster generator definition working properly.... i've viewed all the tutorials, but it never does what its supposed to do.... i cant even start a roller coaster track. i click control point, nothing happens. i click track, nothing happens. if there is any help, i'd be glad to receive it.

My MTA server says that my router ports are all closed.... even though all of them are open..... is it my router? the server? my pc? ive had this problem for a couple weeks now.... if someone could help that would be great
