Did you check that your include paths are correct?
There should be no need for changing any paths, as long as the "Space Shuttle Ultra" folder is inside the Orbitersdk folder.
managed to install but it wont load in im getting this string of errors can anyone shed light on them ?

right cracked that problem one more big issue, so I load up the Atlantis test mission and it just boots out, no error logged the only thing I can find in the log is this ...000000.000: >>> WARNING: Obsolete API function used: VESSEL::CreateVariableDragElement
000000.000: At least one active module is accessing an obsolete interface function.
000000.000: Addons which rely on obsolete functions may not be compatible with
000000.000: future versions of Orbiter.g any ideas why it could be booting out?
