Looks like you are using an old v2.5 64 bit, you should anticipate lots of problems heading your way.
Here is the 32/64 installer, Avisynth+ v2.60 r2664-MT:-

Or Groucho2004, multi-version (universal) installer:-

DirectShowSource is not frame accurate, so will probably cause problems, use only as last resort.
