我前天还做了一部分题，今天一打开，说是 System Date Mismatch。 下面是error
message:
The system date on your computer seems to have been changed unexpectedly.
It appears that the system date has been turned back since you last used
this application. This application requires correct system date to operate
properly.
Please correct the date on your computer and start the application again.
从来没碰到过这样的问题，着急。点开右下角的时间，日历是对的呀。请问大家碰到过
吗？怎么解决。谢谢！
