I experienced such problem with previous FST versions on VPS. The reason was that other user with the same ID numbers interferes with my connection. The latest FST codes also the VPS user name in the connection to MT4 and this problem was solved. You can easily test this case by stopping the experts. If some of your FST copies is still magically connected to a broker, it means that the connection comes from other user. (Ohh windows, windows what shell we do?)
Anyway, the problem is only in the VPS. See the attached program, you can monitor the connections with it. Each FST - MT makes a so called named pipe. The named pipes in this example are:
MT4-FST_Popov-120
FST-MT4_Popov-120
where Popov is my user name and 120 is the ID number.
These pipes are channels for connection between MT4 and FST.
You can see new pipes for every connection you use.
Check it, some useful info may appear.
