Check your address in the block explorer (blockchain, blocktrail etc.) if the transaction is there if not the bitcoin is still on the receiver's address . If its confirmed there . Uninstall your armory and install it again after that import them again since you said you backed them up . Because if its already confirmed the problem lies on the walet, maybe its not synced . Did you install the compatible version for your pc?
I did just every time I try to run the program I get a data base error. Thats why I wanna try installing ubuntu tonight and running it on ubuntu. I tried armory on several computers all had the DB erorr. And my bitcoin core is synced.
