我按照所说的注册方法注册的，可是注册后出现这样的错误：your system clock appears to have been set back ,possibly in an attempt to defeat the security system on this propram correct your system clock befote trying to run this propram again .if your clock si correct,please contact the author of this program for instructions on correcting this error
以后就不出现要注册的画面了，请问是怎么回事？
