Did you use that directly with ExpressPCB and order from ExpressPCB or 
did you convert to more standard gerbers?  (This thread has me 
motiviated to maybe get my 11/45 running again next year, and verify or 
fix my FP11-C)

[Note,  I have also been corresponding with the OP on purchase of my 4 
"spare" boards for an FP11-C]
