Build has nothing to do with it. However, you probably should not be running BP builds for anything other than BP... I know ya'all want deferred lighting and shadows and all that jazz.. but damn.. can't anyone (including the BP team) just wait for things to come down the pipe with full testing.. sheesh..
I'm nearly positive that your issue is do to your HUD resolution and the fact that FSPort probably didn't consider it when building their HUD tables. I can't view the files currently, but you can try to rip out the hud_gauges.tbl or -hdg.tbm and make a single line change that should fix the problem. (Save to fsport\data\tables.)
Find $Required Aspect:, $Min:, $Max: in the tbl/tbm. Make sure that the aspect is widescreen and that the min/max values include your resolution. To that end, you can just remove $Max: and it should solve your problem.
No, it's not your mod.ini either. Don't change that.
