One thing to remember, the FIA times vary for each regional server. I have my original account on the NA server but live in the EU. Everything is ok except FIA races don't start until 0200 CET which makes racing mid-week a royal pain (weekend races start at 0000 CET which interferes with my racing with friends). I personally opened an EU account so FIA racing was at a more reasonable time (which now starts at mid-week1800 CET/weekend races start at 1600 CET). If FIA racing is not your thing, you can access racing with NA server based friends without opening a second account, just open up ALL servers in the lobbys. Hope this is useful.
Enjoy your racing!
