Bummer, ran into my first problem.

Fatal error: Uncaught exception ‘FacebookRestClientException’ with message ‘Incorrect signature’ in /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/facebookapi_php5_restlib.php:378 Stack trace: #0 /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/facebookapi_php5_restlib.php(79): FacebookRestClient->call_method(‘facebook.auth.g…’, Array) #1 /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/facebook.php(84): FacebookRestClient->auth_getSession(’4aed0976c07b034…’) #2 /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/facebook.php(75): Facebook->do_get_session(’4aed0976c07b034…’) #3 /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/facebook.php(51): Facebook->validate_fb_params() #4 /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/appinclude.php(6): Facebook->__construct(’200172bb47a151b…’, NULL) #5 /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/index.php(2): require_once(‘/home/.pax/dlif…’) #6 {main} thrown in /home/.pax/dlifson/socialstartups.com/f8/recentpurchases/facebookapi_php5_restlib.php on line 378

Got as far as step 15 on http://tperry256.dreamhost.com/f8/tutorial/, lost it at step 16.
