Try bumping the temps up a notch. White labs says optimum temp for that is 52-58F and you are at the low end or below:http://www.whitelabs.com/beer/strains_wlp820.html
My lagers do well if I go by WL's recommendations.
I don't think you are screwed. Give it some more temperature and perhaps pitch more yeast. I do tend to do big starters, but for my first lager I used one vial of WL's yeast without a starter and it had no problems once I got it going at a slightly higher temp, then crashed it to normal fermenting temps. I left it at about 68 for 8-10 hours, then into the lagerer...
