WE may be running into another problem we've seem recently. If you've been a long term user of TeXShop (i.e., back quite a long time) your (pdf)(la)tex settings may be wron which leads to problems when you run into an error showing up in the Console window.

Please go to the Engine tab of TeXShop->Preferences and click on the two `default' buttons in both the pdfTeX and TeX+dvips+distiller sections of that page (four buttons in all) and see if that fixes the problem.

Good Luck,
