mega vocab

I am having some trouble with mega vocab I get an option correct ie pez and on the next page it says pez again even though there is no picture of a fish so whatever answer I give it will be wrong and I have to go through all six cards,It is doing this at random with quite a few words. I have deleted the program and re-downloaded it but this still does not resolve the problem. Any advice would be welcome :(

Hola Duro, Thanks for the advice, I recently had another report of the same but I thought It might have been an isolated case... I will get onto it straight away and let you know when a fix will be done. Thanks again Mauricio
