I've seen several people having this issue. I too had this problem with an older machine. I put this information on the download instructions, forum, and main page.
If you get the error:
FATAL ERROR in Vertex Shader compilation
try updating your Microsoft DirectX Library from here:https://www.microsoft.com/en-gb/download/details.aspx?id=35
