Possibly try reinitializing VW first, but you will lose the files in your queue. You could also try importing them into VW a different way, drag and drop or simply opening in VW instead of dropping them into the folder through flexi. I don't think that will help, but doesn't hurt to try. Also when you go to printer and setting in VW does it show it's connected to the printer? Is the ip address correct? Last resort would be an uninstall reinstall of VW but I would imagine reinitializing and checking to make sure it sees the printer might help.
