try:

LoadCPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\ffms2.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\SupTitle.dll")
FFVideoSource("D:\Aquaman.mkv", fpsnum=24000, fpsden=1001, threads=1, colorspace="YUV420P10")
Preroll(video=10, audio=0)
SupTitle("D:\Aquaman.sup")
return last

the Preroll (http://avisynth.nl/index.php/Preroll) is important for stability when using SupTitle.

If that also doesn't help, upload the subtitle file somewhere and share it with me.
