Hi,
you can try this,it's a crude method but gives you directions but no countdown markers/numbers.
Replace the tgs.gau with the tester gauge that ships with PFE and re-name it tgs,when i tried it,the gauge lights up and as the green pointer putting you in the general direction of your runway.
I take it you have re-loaded your aircraft that it fails to load in and also try position it at 000 , 000 co-ordinates...which puts the gauge in the top left hand corner of your screen.
You could also re-run the accumulative updater again,with regards to the displayer you have to start PFE and then the TGS displayer is activated and is configured as per instructions in FAQ's
