As I am fairly new to trainz please excuse my sometimes irrational behaviour...I know this problem has been aired before and I have just spent ages looking through past threads for a solution to my particular problem....There seems to be numerous varieties of it so here is mine... When I go into surveyor and choose one of my own sessions to play with I get the familiar black screen telling me I have some custom content not installed etc etc...I've tried using a session that does not get this problem and simply changing its name using "create new session only".When I try to use it I get the same old black screen even though the only thing I have changed is the session name...So does surveyor dislike certain names or what..I have tried numerous new session names including some obcene ones and some times it worked and others not (it didn't like the obcene ones by the way)Did I spell obcene right?....
I know that all I have to do is ignore the screen and it will go away and things work ok anyway but it still gives me the screaming wombats when it happens.....I am using trs 2004 by the way..I have several sessions that have never had this problem so I went into them , put in something that was already there and saved it with a new name only to get the missing assets message when I tried to use it...
Hope you can shed light on this and help a silly old fossil out...
thanks to all..
