in line width i typed 0.5, other options became available, nothing to select in the P3D window, in main texture i select 'gp_yellow_20f'. As i understand it if I do no more then the texture will just tile/repeat, as it is a solid yellow line i want this is fine, at this point I click ok.
Back in the main ADE window I click 'Compile', in more options i have selected to (compile 'with project file'), (Save Xml 'Don't Save), I check 'Compile separate airport and object files' in the lower ' conditional compile window' all options are checked.
Back in main 'Compile Options' window I click Compile, ((ADE_GroundPolys) )Invalid version) message as two posts above, I click ok, get the message ((GP Compiler) The GP Compiler reports that it failed. This compile will now be aborted.)
Not long been back to ADE after a trying it out last year, I'm sure I have had it working before but can't remember if I had issues back then.
