急！我在windows2K下安装了php，apache，mysql，当我开启apache后
打开php文件出现了以下错误？请指教！
Warning: session_start() [function.session-start]: open(D:\PHP4\sessiondata\sess_18403d8254d5d0c3ccf92f121a4e0aae, O_RDWR) failed: No such file or directory (2) in d:\apache\htdocs\lltj\register.php on line 2

下面是我的源文件摘要：
<?php
session_start(); 《-------这就是第二行了。
?>
<TR>
<TH BGCOLOR="#d0d7af">
<DIV CLASS="text"><font color="#ff0033">*</font> 联系地址</DIV>
</TH>
<TD COLSPAN=3 BGCOLOR="#fafafa">
<DIV CLASS="text">
