Unable to Access Resource Error in AE CS6

Hello,

I'm running After Effects CS6 11.0 on MAC OSX  and everytime I attempt to apply text, either by creating a new text layer from the drop down menu or dragging open a text box I get

"Unable to Access Resource    P_TextSmallCaps_Sm_N_D (type png)"

Is this a png file missing from the program, a fixable bug or what?

Any help at all would be greatly appreciated. Thank you.
