"Waiting for circuit"-problem (newbie)

[Buchenstab]

Hello!

I'd really like to use Tor but I have the following problem that I  
couldn't solve although I searched the FAQ and Wiki for days by now.  
I'm not so familiar to this advanced use of my computer (for ME it's  
advanced)- so I hope, someone can help me out?!

The log:

information, but not enough to build a circuit: We have only 96/1201  
usable descriptors.

usable descriptors.

information to build circuits.

I'm running the 0.2.0.31 Tor pack (german) on MAC OS X 10.5.5 with an  
PPPoE internet connection (account name + PW). The whole package is  
installed, but as soon as I want to start Tor, I've the listed  
problems. Did I forget to make more adjustements than installing it?  
The Tor site doesn't say more to this. Do I have to install a proxy  
internet connection?

Hoping for some help to a poor newbie who wants to learn how to surf  
more securely and also wants to enlargen the network
