Thanks Nick,
I'm sure it won't affect many users but may do in time. My scenery updates seems to run cleaner now. The makerunways version is actually something like 5.1.2.6 or similar even though it says 5.11 if you need to be sure just redownlaod it.. It was updated to try to fix this error but couldn't seem to fix the anomaly with non standard characters as those found in LFLL.
Thanks for taking a look.

A note for simstarterNG users, after making the above changes, accept the new addon and let simstarter auto update its references to as it believes you have installed new scenery as the scenery url has changed
