getting error when activating

I got this exception says unknown protocol: c after I have successfully installed MatLab and starting to activate it.

The log file says: 八月 12, 2015 10:15:18)Starting activation process. (八月 12, 2015 10:15:18)Performing interactive activation. (八月 12, 2015 10:15:19)MATHWORKS ACTIVATION IS STARTING UP.

Please contact Mathworks tech support via phone or email.

This issue can occur if your system (eg. Windows) username contains special characters. To resolve this issue, try creating a new user account without special characters and activate MATLAB for that username.

If you have no special characters in your username then, as Muthu mentioned, you should contact the MathWorks Technical Support.
