Cannot use _FFWindowSelect with different Firefox profiles

Hi, I have a problem with working with different Firefox profiles. I  try to open a few firefox windows and try to manage them separately with autoit. I run 4 programs, each program open a different FF window (with Run command) but every other _FF operations are working on FIRST OPENED FF window. I wrote one program (file included) where I try 4 times to open one window, using the profile no $i, use _FFWIndowSelect() to work on this instance, try to open any webpage, open the next open (success) and to do something in this window, but it does everything on FIRST window. I tried to replace Run() command with _FFStart(url,no of profile,9) where 9 is 1 (new window)+8 (-no-remote - neccessary with different profiles) but I got a message('Firefox is already running but do not answer. To open a new window you have to close existing firefox process or restart system')

How to open FF window with desired profile and work on it?

I tried to include _FFWindowSelect before _FFConnect() command but it does the same result.
