Thomas Ruth 727-200 missing nav and strobe lights

hello all, i like flying the toms 727 very much but the lack of nav and strobes lights is very disturbing, ive seen in a previous post that someone downloaded the tom7272.zip and fixed there problem but that did not work for me, any one has any ideas on how to fix this ? landing lights, becon & logo all works find by the way.  I also use FSX steam edition so im not sure if that causes the problem, checked online for any cfg tweaks and found non but anyway if anyone has a idea on how to fix it please reply thanks.

Andre.
