Yes we have the same traffic and airport files
We have do a fresh install and no changes at any file.
I do a new install on the computer with the server (Computer A) and then i do the same at the client.
Install all stuff of tracon on computer A and B and the same for tower.
Both computers with connecting with tracon (B connect to A both Tracon), no problems
A start server and B Tower will connect to A tracon then i got the XML error.
Again all the files from both pc's are from a fresh install so i think that files are the same on both computers
Say i start New York as server i give the time etc to B the tower
Both PC's have New York as Tracon and as Tower
