To find a design in DBC is easy if you have not renamed the file. They all have numbers. Copy the number only that you have, go to DBC, pull up one design (it doesn't matter which one), replace the number with the one you have copied into the link followed by an /. If you need help PM me.
P.S Found it for you
What is the number? Maybe someone else can also look for you. Love Chris
You could try typing it in the "googlecustom search" just to the rightand under the "Ask the community" place.
Out of what category? Is it from Design by Cuties?
