[A no copy object failed to rez inworld and disappeared from my inventory, how can I get it back?]

I bought a complete avatar at Marketplace and received my purchase with no problems. I then went to a sandbox to rez it inworld....waited...waited some more and finally got the error message, "object failed to rez". The box was no copy and is no longer in my inventory nor is it inworld, where did it go and how do I get it back?
