Taxiway signs should always show up. As far as I know there is no image complexity option for them. Do your taxiway signs show up in other airports that you have not modified? Did you make any hand modificcations to the xml or use another program besides FSX Planner that may have modified the xml in some way?

No, i dont have the taxiways showing up in anyother airport except Stansted (I have UK2000 Scenery Installed).If i cant change it so they can be viewed in very sparce scenery level then is there a way of getting rid of the auto generated scenery from FSX?
So Stansted is the only airport in the entire 24,000 airports of FSX that taxiway signs show up for you?
If that's the case then perhaps when you installed Stansted that caused a problem or conflict? I'd try rempoving the airport to see if it changes anything.

He means that to see taxisigns at all airports he has to put his scenery up high, the only airport he can see taxisigns with having his scenery down is Stansted becuase he has payware scenery for Stansted.
If thats not gunna work then, is it possible to remove existing buildings from FSX? Like hangers, so I can then replace them with somthing else.
As billy said i am using UK2000 payware Stansted Scenery.

Yes it is an NVidia 5000 series and some of them have problems with displaying FSX elements.
There is a known issue with nVidia 5000-series cards displaying taxiway signs in FSX. Actually it is that the taxiway signs don't show up at all, or display all white.
I don't have a 5000-series card so I can't tell you exactly what it looks like.
Hi,
NVIDIA GEFORCE FX5200
That problem was superseded with SP1. Before, I could only see taxysigns at night. After SP1, I can see them at day or at night, without problems.
