I updated ConTeXt standalone again and test it. The result is same as before. In the log file, it located the font but it issues the luatex error. The font version is 1.001. The only difference of the luatex which I can see is that (mine: Standalone, rev 4972) and (Luigi’s: TeXLive 2014, rev 5041). Does it matter? I may test it under TeXLive 2014 which I need to install it. Thank you.
