Is there something interesting in the log I sent to yaobing?
The log shows that MC went through license acquisition and a very generic failure code was returned. There are also a few lines of logging that are missing (maybe due to multiple threads fighting for the access of the log file).
Did you get a warning dialog box about needing to acquire license?
EDIT:
I see this in your previous post:
1- MC showed me a dialog asking for something. I did not pay attention and pressed OK...
Could this dialog be something like one of the following?
"The license acquisition URL in this file has been tampered with.
You are strongly advised not to navigate to this Web site.
Navigate to this Web site anyway?"
or
"A license is required to play the selected content
To obtain the license, you must visit the content provider's web page.
You might be required to register or pay a fee for the license -- it varies by provider.
A web page can contain elements that could be harmful to your computer.
It is important to be certain that the content is from a trustworthy source before continuing.
Are you sure you want to open the web page to obtain the license?"
or
"The license acquisition URL in this file is not signed and its validity cannot be guaranteed.
Get a license anyway?"
