用W32DASM装载程序，先用串式数据参考(String data refs) 检查程序。 <br>
你运行crame时，选择任一文件，则出现:"Invalid Keyfile"，因此在W32DASM查找这字符串，双击来到W32DASM中，向上会看到：
<br>
<br>
* Possible StringData Ref from Code Obj ->"Runtime Error: 12FF:024"
<br>

<br>
不过你们看到上面的字符串: "Runtime Error: 12FF:024" ，真有点奇怪？难到是程序的BUG？再激发点灵感，是不是keyfile文件中的Keywords？
<br>
试试吧，建一文本文件，把Runtime Error: 12FF:024这一行放进去。运行程序，选择你刚才建的文件，OK,这下没出现错误，成功！现在程序充许你键入name和code。你任意输入点击OK,出现:
"Wrong Entry! Try again!" <br>
