Rich,

Compiling your MWE, I did not run into the error message you mentioned. 
I did get an "Undefined control sequence" error for the line 
"\pagestyle{headings}", which I believe is caused by the fact that the 
Modern CV class, unlike say the standard article class, does not define 
a heading style. In Documents > Settings > Page Layout, I changed the 
"Page style:" selection from "headings" to "Default", after which the 
MWE compiled. (Whether it looks right is left to the reader as an exercise.)
