No, then you would need to find tools.php, it's just that I'm fairly certain that you won't have that problem.
If you download the distribution zip file for your version of vb (if you don't already have it). When you unzip it, there should be a "do_not_upload" folder, and in that folder there's a file named "tools.php". If you need to you can upload that to the admincp folder on you server, then in your browser go to "www.mysite.com/forum/admincp/tools.php" (using your own domain name and forum path, of course). You then need your customer number, the one you use to log in to the vbulletin.com customer area. After entering that, there's a "Reset Cookie Path" link you can use to reset it.
To make things more complicated, if you're running version vb4.2.0, tools.php doesn't work. Here's thread about that:
