fs2002 problem

When trying to open fs2002 in past couple of days, I now get a message
saying that it has detected 3rd part software that may not be compatible
[nothing added since I loaded fs2002 a couple of years ago].
The problem appears to be File: traffic.dll and it gives me 2 options to
either load or ignore [yes or no]..both options have same affect which is to
log the opening screen of fs2002 off completely.
I have tried the fix which is suggested in Readme but that doesn't work
either.
I have uninstalled and reinstalled the programme but still get the same
message when I try to open flight sim..
It also appears that ..traffic.dll..is a part of the M/Soft programme
anyway..!!!!!!!
Can anyone PLEASE suggest what I can try now..?????
