Drop Shadow Appearance Missing
so... I have a piece of artwork about yeh big... 8.5X11 that I want to resize for a sign project to be about 59"X88.5". I don't have trouble doing so but when I resize... all of my drop shadow effects are gone and I get a message that says "an error occurred while processing the appearance of an object" Now my art doesn't look cool. Any idea what is going on or anyone suggest a workaround...
