I'm sorry to hear that.
Though it is generally aggred in German lager brewing that the wort should be pitched below the fermentation temp, I don't recommend this method for homebrewers brewing their first lager. It does take some additional work to grow enough yeast and the lag times are longer too.
Next time I recommend that you brew a lager, make a 2L starter, aerate and pitch one vial or smack pack into it. Keep that in the upper 60's and don't worry about the sulfur smell that might be coming off that starter. Many lager yeasts do that. Once you have high Kraeusen pitch this into a well aerated wort at about 60-65*F. Once you see fermentation start lower the fermentation temp to 50-52 and let it ferment there. This is what is usually refered to as warm pitching and it is fairly fool proof. If fermentation stops after you lowered the temp to 50-52*F you lowered the temp to fast and shocked the yeast into dormancy. Let it warm up a little and it will get going again. Then lower the temp more gently.
Once that is working for you and got hooked on the debutants, e.g. lager yeast, you can try more advanced techniques like cold pitching. A good book for lager brewing is Greg Noonan's "New Brewing Lager Beer".
Any disgreement from Jamil or Dr. Scott?
