Well, Hi again pete, and thank you for taking a time to see my problem.
First of all....
How things started..
My machine (laptop, sony vaio pcg-gr390) was running originally on winxxp (home), and I had installed fs2002 long ago, and everything was running super! 1 month ago, I bought a hp printer, but it required I had SP1 in order for the printer to work. So, I did my search and I found and downloaded sp1 (around 130mb), installled it in my machine, the printer worked, and everything was working fine with the sp1 installed. It was NOT an update for fs2002, but for the operating system (XP).
However, when one day I tried to run fs2002 (that was already installed in my machine), that pop up message appeared (the one i described in my first message) asking me to add or not the new software etc.. Whatever I did, the fs2002 was shutting down on me right away...
By the way, the two files fs2002.exe and traffic.dll have the same version (the same with yrs).
When I uninstalled the fs2002 after I had installed sp1a (thinking I could resolve the problem), I of course deleted every folder of fs2002. and fs2002 folder too. complete uninstal.
So, no corrupt file involved, no version conflict, no installation procedure error..........................What else can it be..?
I am guessing it has to do with some kind of conflict with the sp1 that I installed.
Thank you for your support so far peter, any new ideas always acceptable...
