There is my test.rb:  
require ‘yaml’  
config = YAML::load(File.open(“config.yml”))

and there is my config.yml:  
topic: forum-39-thread-11173510-1-1

“mkexy test.rb” and “exerb test.exy” can execute all right and generate  
test.exe,  
but when I execute test.exe,it raise an error:  
yaml.rb:9:in `require’: Win32API Error #127  
(ExerbRuntime::Error)  
from yaml.rb:9  
How can I fix it?Any help will be appreciated!
